Many people lock up in such situations and can barely say their own name, yet with the right approach it’s a non issue. Netflix's competitor is just one of many subdivisions in Amazon, after all. Okay?". In my experience the leetcode questions were quite easy from an algorithm standpoint: string operations and traversals and things like that. etc. New Services(Self Onboarding). And that 1% of the time you do? Do you get flustered under time pressure? Ironically, the last thing that Facebook engineers want is for the government to regulate them. You’ll certainly be able to secure a seat at Amazon. Amazon isn't great environment in most of the pockets of the company (haven't worked there, but worked with a lot of people who came from there), so it's quite possible that you "dodged the bullet". FB has thousands of employees who write code. Really bad analogy. Excellent! I am fully confident that if I had to re-interview for my job today, without extensive pre-prep like the author suggests, I would have a very slim chance of passing. As an interviewee you should have known what interview process is like, I worked at Amazon and I know the recruiters brief the candidates on what to expect in the interview, so you should have known going in that you'd be expected to write code, you could have said no right there and then in the email instead of hanging up on the guy. You need to engage with people without letting things get confrontational. Compare that to the rapid fire technical questions I have watched people get into and it’s obvious what’s going on. C# is about as close to Java as they come. All I learned from that encounter is that I'd be very unhappy working with people like him. If the answer to these is yes, that's sufficient to pass the coding interview. There are too many people who are doing things for $200 that should cost $1000. In this second round of interview, they will give you coding problems. Agreed, just because you're a senior engineer with decades of experience doesn't mean you shouldn't brush up on general fundamentals every once in a while. But it’s simultaneously hard to find better alternatives. I assume you're referring to your ex's exam to become Board Certified in her specialty, which, if you are, makes this statement incredibly hard to believe. Behavioral. I described verbally how I would do it, almost line by line, in pseudo-code. I came in to FB just shy of 20 YOE, and I consider "Google" to be a valid answer to that sort of question. The interview bar for algorithms is probably too high at some places, but those skills are relevant for all engineers. The problem is the "verifiable credentials" vary widely in rigor. (Sure, there is a good deal of overlap, but there is a good deal that isn't either.). Or something like that, but he didn't have any kind of friendly or diplomatic response, maybe I was feeling impatient that day; I honestly can't remember because this was like 10 years ago. In most cases writing low level solutions from scratch is not the best practice. Systems design questions prompt you to architect things which may be considerably different than you deal with during your day-to-day. There's also a behavioral loop and a system design loop, and both of those are extremely important as well. Scala/Kotlin is excellent if you write it like Java. I'm not saying it's the best long-term or that I agree with false positive bit as a business decision, but I find it hard to believe they're doing stuff like this just because they feel like it without any data to back it up. Verifiable credentials mean that you pick up a phone and call the references the candidate gave you. people giving interviews) have an incentive to not let people in too easily? They'll all be very specialized. Computer science literally has algorithms. One is: Talk to the fucking candidate and ask them about the things they have done over the course of their career. You want to check my computer science background, ask me about: regular languages, LR0 grammars, interpreters, compilers, system calls, threads, virtual memory, concurrency control, TCP, consensus protocols, raytracing, scene segmentation, sensor fusion, database indexes, block cipher padding schemes, etc. I said "But why? anatomy, physiology, etc.). And tailor your plans wisely to execute them smartly. For better or worse, when you get to a certain size you absolutely NEED that level of bureaucracy. Though exam subjects changed over time, it typically included recitations of Confucian poetry, calligraphy, instrumental music, and other such gentlemanly subjects. I feel the same. This is common to all professional disciplines. In other words, things that are absolutely relevant to the actual job. So far at FB I have coded in 4 different languages and picked up all of them as I joined teams. But we had 3 devs. We hired one who couldn't. I've never once had to write a low level algo implementation. Candidates who have them get hired after a few interviews, candidates who don't have to do many more interviews to find a job (or get discouraged). When a candidate struggles, I gently lead them and help move things along in a very collaborative way - I am also very tolerant of mistakes or poor starts and proactively give every opportunity for those to be discounted. Asked me to write some kind of function to do something, sort some stuff or some such. I'm sure Netflix is a "wealthy" company with a competent engineering org, but surely they are nowhere near the scale that the rest of the letters operate in? They just need a large group of developers who can do the work, and a small group of developers who can push the envelope on the most cutting edge stuff. This doesn’t happen in any other context in software engineering except interviews. Phone. So I thought the main point of the poster I was replying to was to take a dig at Facebook. If there were poor doctors who had to drive for Uber eats after hours we would be hearing about it. They also helped enforce a common culture, script, and style of writing for the large empire. The medical credential stigma is real- nurse vs traditional school vs osteopathic school, many of which have been closed to specific races or gender identities historically. Same with lawyers and accountants (accountants have so many certifications it borders the ridiculous). The only way to measure the value and experience of senior developers reasonably is to have in depth discussions about their experiences. I did a lot of interviews (as interviewer) at a non-fang-but-close-enough, the guideline was to tell interviewees to pick the language they most prefer. 4.1- Why did you switch your last company? You don't have to agree with me. I think this is an equally poor analogy as it assumes Facebook wants to hire all the good people it can, which isn't the case at all. Software engineering does this better than most fields, even if it sometimes leads to really bad results like not hiring Dan Luu. If you are a serious Software Engineer with 15+ years of experience you will easily fail their stupid interview process. But the engineers at FB do need to be able to write sorting algorithms from scratch rather than just have knowledge of sorting. One suggested alternative, take home exercises, became a mess because a lot of companies, and individuals at companies, started treating them as free labor. Demonstration of technical skill is absolutely crucial for an interview. If you are lucky to work on open source for your job, it is easy to show your work. Despite my 15 years of professional experience and a deep understanding of their tech stack (which, of course, was not a main discussion point at any stage of my interview process -- one of many red flags for me), if you had watched this you'd have thought I barely know how to write code. Interviews like these don't find cooks, which is somewhat the point. They do need to retake their boards periodically to stay certified. There is this weird meme that using Python is beneficial during interviewing -- you mention it, the OP mentions it, I have experienced it myself and seen friends mention it. It sucks that I would have to study for weeks to not flop these interviews even though I consider myself a good software engineer. Conducting a full interview “without letting things get confrontational” is difficult. You can say “at work I’d look up a reference” but in an interview setting that’s not helpful where the interviewer needs both. It's not like this was posted on Facebook's blog - right? I described verbally how I would do it, almost line by line, in pseudo-code. 5.2- Bar raiser is like a pair coding round. It is definitely not all of the experienced candidates who fit that profile. I was going for people scratching their own itch during their OSS-at-work time and wanting to show off - but this could very well be a better explanation. Our academic team adjusts to the market demand. Instead we only get to see their practice pieces. And I don't think Facebook requires its engineers to re-interview for their own jobs every x number of years, so that's disanalogous too. This is done to avoid bias and/or favoritism. > The author is basically just putting out a detailed study plan for passing an exam. > I'd argue that points to a massive monoculture problem at Facebook, but I'm massively anti-Facebook so I'm biased. Interview. This may be an unpopular opinion, but I like how it is very objective, measurable, and somewhat specific. my experience in the industry of coding has driven home to huge points: It's sad but yeah it's true that you have to prepare for interviews. Oh, and they don't get paid at all until they start residency rotations which is AFTER 4 years of med school, and their pay during residency is on the order of $30k-50k for what effectively amounts to 80-100 hours a week. Doctors don't need that stuff outside their specialty... until the day they do. Massive enterprises like Facebook have no need for creative "outside the box" thinking anymore. 4.4- How can you contribute to the quality of the product? Small startup involved wearing many hats, but in general was a more specialized role than FAANG. Virtually every FANG interview I’ve done has covered API design as part of system design. I couldn't disagree more with your post. Basic analytic skills and data structure knowledge will help you in clearing the round. And why are we surprised? Minimal competency screening is abstracted out to a reusable, memoizing, component. Interview. Question3: What do you mean by the term Frequency-Hopping Spread Spectrum (FHSS)? Medical boards are at the specialty level, so there is no equivalent. I think we agree that if you are in a senior engineering role, I don't necessarily care if you can implement a linked list in an interview time slot, but I sure as heck care that you know how it's different from an array, how it generally functions, when you would use it, in what situations alternatives might be better, and so on. Tough. That seems like a ridiculous stretch in my opinion. Indeed, I've heard from many sources that Amazon is a toxic environment; I have yet to hear anyone say "Amazon is a terrific place to work! I don't think it's unfair to say that Google and FB are considered to have strong engineering talent. "No obviously I have never encountered coderpad in my 20+ years of writing software and will have a hard time using a simple online text editor." These days I honestly think that a developer who is marginally above average but plays well as part of the team is much more valuable than someone super smart who isn't a team player. If you're the one copy pasting code, aren't you the cookie cutter software engineer? Everyone is a language designer? If it did, I think a lot of these kinds of interviews that companies do would not be necessary. These are what our systems are made of and understanding them is valuable to do the work we do. And then think of an optimal solution. Typical success ratios were ~1:50 exam sitters. There was no affiliate link in the original post. Among many other issues, they measure peak performance, rather than sustained performance. All Career Q&As . 5.1- It’s a kind of an open round where the candidates get to answer a variety of questions. IMO the interviews test that you can fall in line and follow the patterns that have been in place for decades. The interview was conducted over coderpad, and at the outset, the interviewer asked if I was familiar with it (I was; I've conducted interviews over coderpad), and I wasted a lot of time commenting out the interviewer's cut and paste instructions and writing out the tests, because when I wanted to actually test out my code, to my surprise, execution was disabled!! You will most likely need to pick up the game and it doesn’t have much to do with your day to day job, but it does say a lot about your ability to pick up new skills/tech ologies. Because it is apparent to me that Instagram, WhatsApp and stories are not innovative. In other words, it's not a standard job interview technique for doctors, it's a one-time requirement for licensing. [0] https://psmag.com/education/be-a-good-doctor-study-the-human... At a company Facebook's size - a random Senior Engineer doesn't carry that much weight. I politely declined; was heading off to Spain for a long weekend. You are judged not just on correctness but also your communication, requirements gathering, ability to catch edge cases and bugs, and general code quality. This is a poor analogy. You have a set of logs and the source code to look at. However, that doesn't mean you will have the prospective hire sit in for an multiple hours/days of redoing university examinations during an interview - as it seems to be the rule in software engineering (and pretty much nowhere else). It's a way to artificially limit supply, to prop up wages for people on the inside. Just disappointed that a great company would have such petty people vetting applicants. The hourly rate for a senior engineer is only about $150-$175 per hour. Hmm.. this is how I got hired last year. No unfortunately, didn't even see that when I pasted. Tooling/languages are standardised, but FB does not care whether you do know Hack, or JS. You're just projecting that, maybe based on bad experiences you have had. I don't find that a useful metric as it implies a huge power imbalance in their minds... nevertheless, sometimes hiring processes make you jump through hoops just to prove that you are willing to do so. Or does your theory stretch to them somehow having short-term memory loss? Interview procedures based around it completely fail to assess some of the most important abilities in software engineering, like API design. Why do people insist on shoe-horning in Netflix in there? Leetcode, while being pretty useless in the real world, does get your brain into "answer hard questions under pressure" mode. What about traversing a tree? For what it's worth, I don't think he'd disagree with you. After 1 year at FB you can switch team any time you like and your manager does not even need to know what you are working on (it's probably better if they know, as they could many times help you, but no one is micro managing you). Here is a list of example test scenario asked during such interviews. (Microsoft, Apple, Netflix, Google, Amazon), > $MANGA as well. I don't work at Amazon and I'm having a wonderful day :). Same with medicine. That's exactly what is wrong with software engineering hiring and interviewing. I don't see a correlation between product growth and engineering complexity. I think that right there is a good enough reason for them to do it. Interviewers definitely want code that works, but being able to do the other things is equally important. It's easy to gloss over details and edge cases when talking through an algorithm and it's not apparent until you actually write the code. The point is that when you write out the code, there will be several other people who will end up looking at it as part of your “packet”. They have a much stronger credential requirement, so if it isn't working for them, it probably won't work for hiring software engineers either. Because you tend to work on tiny parts of a massive whole, there is no tolerance for cowboy-coding and not following best-practices. Yeah, you're getting a lot of pushback from the corporate drones on here, but you 100% made the right call. Yeah, one consequence of hiring exclusively based on technical skill is that you end up with some employees that are empathy challenged. If someone doesn't need to do binary math or write complex sorting algos from scratch you don't test those, just like how you wouldn't ask an athlete the mundane questions I posted above. I have respect for the doctors, but I definitely do not envy their position. The performance problems I've been called on to solve, I solved by having a vague idea of what's going on at the OS and network level, something that apparently makes me a wizard at a company that allegedly selects for "CS fundamentals.". But their work-life balance and the entire process where you start your "real work" after the age of 30 with $200-300k in loans, at that point, isn't something that a lot of people consider when they think "those doctors are having it nice.". If the interviewer is immature, arrogant, rigid, etc., and regards the interviewer-applicant relationship as an antagonistic one, and views the applicant as incompetent and dishonest until proven otherwise, the interview will have that flavor. How much did the anesthesiologist help, above that baseline? Question4: Explain the term Airport in Bluetooth? I have 20 years of experience myself, and I've interviewed and worked with a lot of people with same experience that couldn't code properly (and some of them were actually good engineers). Secondly, programming doesn't have a standard licensure process like medicine. All the big-tech companies work with way too much Java, but Java is way too verbose for coding by hand. I haven't interviewed for senior level positions with FANG. Common. 250+ Wireless Communication Interview Questions and Answers, Question1: How frequency hopping is used for security in Bluetooth? Is it your suggestion that those kinds of applications do not require solid knowledge of a variety of different data structures and algorithms? Yep. there are so few repeatable processes, so few really good ways for a company to systematically remember what any given thing is, how it works, why it works, what it does. > he also seemed unwilling to push at all, just said "okay!" https://www.businessinsider.com/the-ivy-leagues-history-of-d... My issue is that someone at a senior level (yes I realize at some of these companies "senior" means "two years of experience") should have to study for 30 days to pass an interview. > First of all, I'm not sure where this "10 years" is coming from. The hourly rate for a senior engineer is only about $150-$175 per hour. Amazon Quality Assurance Engineer Interview Process and Planning. But if you only read HN you'd think it's a total failure. A "paper tiger" with 10+ years experience (since we are talking a. At my small startup where most of us write an API endpoint, it's important to know. I am not sure whether you have an incredibly good filtering system or have got incredibly lucky. My employer recently added one "are you a human?" And it provides quality references for refreshing that knowledge and for getting practice thinking and speaking about them in human language instead of internal abstract thought. I can so relate to this when I look back at 4 years I spent studying for a CS degree. You rarely need to write your own sort or hashmap, but you should absolutely understand at a high level how those algorithms work, how to analyze them, and the key concepts that go into their design. One of my biggest interviewing mistakes was voting "hire" on a guy despite his seeming difficulty with coding during the interview because he was such a great talker and had great sounding experience. They seem to in construction, plumbing, and trade jobs as well as even acting. So, basically one of the key tools I use in my day-to-day coding workflow was kneecapped. You must not have tried to hire a software engineer before. It's not a skill many cultivate. If someone asked me to whiteboard bubble sort I'd choke. If anything, that attitude would instantly disqualify someone on the “fit” axis of the interview even if they passed on the technical merits. I work with younger folks all the time and 90% of them are perfectly fine; actually I enjoy their energy and drive (and there are plenty of older jerks out there). The entire editing experience threw me really hard and was so distracting that I was fumbling what would've otherwise been trivial algorithm questions for me. 0. of 0 votes. Mostly because Netflix has very high compensation for senior engineers. For every Messi or Ronaldo there are literally thousands of players who were scouted as having potential but washed out almost immediately. I'm not saying the interview process shouldn't be criticized or that it's beyond improvement. She just wished she could spend her time getting better at the skills she actually used rather than a wide range of academic material that didn't matter to her day to day. As someone who interviewed people applying to Facebook (or Oculus anyway), the coding tests were intentionally told to be structured as one easy question (so that the candidate could build some confidence and provide some signal) and one medium/hard coding question (ie can they write more substantial solutions and solve harder problems). If you can describe an acceptable algorithm with enough detail in words, you can code it. Interview Questions And Answers Guide. Let’s now hear from excerpts shared by many of our readers. The author mentions CLRS. We are a smaller org and hire occasionally for roles that are most suitable for early career applicants. Of course you are right, interviews serve as a filter, one wants the newcomer to increase the output of the team, not decrease it ;-). It's basically the final part of your education in that field (and others). And again I've seen enough anxious candidates to see the difference. Then if they pass, hire em on probation for 2 months and slam them with work. It could also imply that they simply get more good applications than they need. It isn't even a second thought to me that I would much much rather study for interviews every single time i switch a job as a software engineer than deal with what doctors deal. text or pdf) from the local machine to a dropbox. You might be among the developers who are planning to advance their career as a DevOps engineer, analyst, or specialist. Facebook, who is paying a lot of people to optimize its hiring processes, has found a correlation between the objective of "lower short-term attrition / first-year PIPs" and "quiz people about the mesh size of the goal net." Plus, if you want to be terse with Python (whiteboard space is limited after all), it quickly becomes alphabet soup. I am a structural engineer and generally enjoy it but the pay is not commensurate with the responsibility and liability. To manufacture a public body of work for myself, I built two open source projects and published them on GitHub. If you want to test yourself, you could try these, which are popular questions: https://leetcode.com/problems/find-all-anagrams-in-a, https://leetcode.com/problems/subarray-sum-equals-k/-string/. Privacy and legal compliance toward evolving laws in a massive codebase + many datasets spanning multiple complex systems is a company-wide effort that takes some serious system engineering ingenuity. At the same time I'm a software engineer, and I could write a database much easier than create something that grows faster than Facebook. I mean, yeah, you're probably right. you seem to be protesting too much. You can't be more far away from the truth. It's an almost pointless interview exercise. However, unless the job actually requires intense face to face confrontation you want to know how well they can do the job, not how well they can interview for it. It's like making a soccer / football player answer a test on the history of the sport, how the ball is made, the geometry involved in kicking the ball, the mesh size of the goal net, etc.
