Entretien

A recruiter contacted me over email and set up a phone interview for the following week for a 15-minute call. I guess next round would have been with a hiring manager

Questions d'entretien d'embauche

  • PLEASE DON'T TAKE THE PHONE SCREENING LIGHTLY! I did and got rejected. I was expecting SQL questions and in general talk about my resume but she asked me a question on product sense and I was completely unprepared for it. Creation of Facebook user groups has gone down by 20%, what will you do? sounds simple but I messed it up so badly. I was just blabbering anything in an unstructured way, I sounded so stupid and not even fit for a small company forget Facebook. The recruiter was nice and she did not say anything but I were to hear my own answer, I would reject myself on spot. I regret it so much wish I could have prepared for it. I hope someone sees this and it helps them.

    The SQL questions were easy and I did answer them correctly- what kind of joins to get only common rows, what the natural sorting order etc.   8 Réponses

    Call with recruiter, behavioral questions. Heard back shortly after. Overall pleasant experience. Didn't make it to longer interviews or superday. All virtual. Asked simple questions about me and why I'd be a fit, nothing too complicated

    First call is with recruiter. Basically they check if you are a good fit to this role. Second happens with HM where he discusses about your work experience, shares about their team's work, ask case study based questions. Third is final onsite.

    The process was extremely well-managed, and the recruiters were very prompt and helpful. They do a great job of preparing you for each step of the process.

    The first round is a telephone screening which was around 10-15 mins long. I was asked a very open-ended question about how I would broadly analyze the drop of key performance metrics and 5 simple questions on SQL.

    The next round, which was the technical screening, took place around 3 weeks later. A similar broad and open-ended product question was posed, and I could not help but feel that the only thing that was being evaluated was my ability to think in a structured manner. This was followed by a couple of relatively simple queries where I was asked to write a code to get a frequency distribution and a simple case-when application.

    The onsite round took place online. The first 2 rounds were very similar to the first round in the technical screening in terms of the open-ended nature of the questions, and the evaluation criteria still seemed to be more of how you walked the interviewer through your thoughts without getting overwhelmed or sidetracked. The technical round was SQL again (though there was no restriction on the language I wanted to use), and the problems where definitely slightly more challenging. You need to be quick on your feet with SQL, I was asked what sounded like a very simple question which actually involved a cross join and some creativity on the spot. The last round was a quant round that revolved around Bayes' theorem, Power of tests, Type 1 error/type-2 error, and imbalanced classification. Intuitive explanations of the math were just as important as being able to solve the problems.

    All the interviewers were extremely pleasant and conversations. Nobody seemed like they were 'out to get you', but were there trying to actually assess whether you could think coherently and whether they would be willing to work with you. It would have been a great experience even if I had not received an offer, but they were kind enough to extend one to me within 3 days of the onsite round.

    I wish there were more to describe, but this is mostly just airing a grievance with Facebook's recruiters. I had a recruiter reach out to me about a month ago for a Data Engineering job. I'm not a data engineer, so no problem, but I had a friend who's at Facebook drop my resume in for a position better suited to my background. I received a rejection email on that position. No big deal. Happens all the time. Last week, another recruiter from Facebook hit me up for a data science job. I said "Hey wait, my friend put me in for a similar position a couple of weeks ago. I think it'd be pretty unfair if he didn't have an opportunity to receive a referral bonus." She reached out directly to my friend and asked him to submit my resume again for this Data Science position and then scheduled a call with me for today. A couple hours before our scheduled call, I received a rejection email akin to the one from a month ago. I replied to the recruiter who sent the rejection and said "Hey wait, I have a call scheduled for this afternoon. What's going on?" and she replied that there was a matter of a duplicate record. Then the original recruiter who had reached out to me totally ditched the call that we'd scheduled. I can handle the rejection. Again, happens all the time. They have something they're looking for and I'm not it. OK, no problem. But the absolute, total, incredible lack of professionalism from Facebook Recruiting is just embarrassing. I will _never_ respond to another Facebook recruiter. On the off chance I actually _want_ a job at Facebook, I'll work through my contacts and avoid their recruitment people at all costs.

    Be prepared the interviewer may start to eat his lunch when you are talking or answering questions. Highly doubted if it was a part of the interview. If you ask me to evaluate it, I would give a negative experience. I think he did not prepare anything for my interview. He probably did not read my resume at all.
    When I started to introduce myself, he interrupted me at the second sentence, so I did not even finish my introduction.
    When I was answering his questions about a FB product, he started to eat food in front of the camera... In the last part, after I asked him two questions, he did not give me any useful information, which made me feel that it bothered him very much to answer my questions.

    I had a video interview with a Data Scientist. The interview lasted about 45 minutes and consisted of one technical coding (SQL) question and a product question. The team member gave me time to ask questions at the end.

    Incredibly smooth process - recruiters are super responsive and accommodating. I got updates regularly as well as plenty of support around the types of questions I would be asked in the interview.
