    Application

    I applied through a recruiter. The process took 2+ months. I interviewed at Facebook (Menlo Park, CA (US)) in July 2019.

    Interview

    My interview process at Facebook was very chaotic. After being contacted by a recruiter on LinkedIn, I was passed through 4 different recruiters during my interview process. While each individual person seemed nice, my experience seemed to reflect my impression of the company as a whole: disorganized and unguided. After intensely preparing for white-boarding interviews, I was ultimately left with ambiguous feedback about their decision not to move forward after the on-site, which seemed largely based on the subjective feedback of a single interviewer. Facebook definitely does not seem like the holy-grail of tech companies to work for that its reputation sometimes suggests.

    The process took 2+ months. I interviewed at Facebook (Menlo Park, CA (US)).

    Interview

    The process went as quick as I wanted it to go. I was initially contacted on LinkedIn and set up a recruiter call. Fairly standard call going over me and the role. At the end of the call I was asked a list of technical questions to see where I stood. From there I was scheduled a tech screen. It used a code sharing site and was a typical front end question, followed up by several variations of the question.

    After passing the tech screen, I was given a different recruiter. After an initial call, an on site was set up consisting of 2 coding interviews, a system design, a behavioral interview, and lunch. The coding interviews were more front end focused (as opposed to leetcode style), and weren't too difficult. The system design interview focused more on finding edge cases, performance issues, and figuring out requirements than I would have expected. The behavioral interview was pretty standard and they did a good job asking relevant questions about me over things you see in "10 STAR questions to answer" lists. Overall, the interviews were easier than I was expecting and I received a verbal offer. Afterwards, I was also scheduled for a few on site meetings with various people to ask whatever questions I had about FB.

    Overall, my experience at FB was pretty positive. I went in thinking that even if I did get an offer I wouldn't take it because of the location and product. After the on site and following meetings, I was impressed enough that I seriously had to consider taking the offer. The reason I rated my overall experience neutral, however, was due to my recruiter being overly aggressive before and during negotiations. Even if it isn't true, I want to believe that the recruiter is on my side. Instead, I felt like they were playing hardball against me. While I left the offices with a great impression, my recruiter left a sour taste in my mouth.

    Application

    I applied online. The process took 3 weeks. I interviewed at Facebook (Menlo Park, CA (US)) in February 2018.

    Interview

    The interview process was pretty standard for Facebook: phone interviews, then one-day session on-site. Recruiters and interviewers were nice and friendly, but the overall impression was smeared by unclear feedback during and after the interview. When they say "yes, great, awesome, cool, makes sense, etc" all the time, it's like "wow, I'm doing great!" But afterward, they reject you saying that you didn't do what they wanted, and you should've been better than that. The architectural interview is one of the most unpredictable, so be careful choosing the way you go. The main problem I see is that interviewers don't give you any hints when you go off the _expected_ thinking direction. They may also initiate a discussion that results in lack of time, and it's almost impossible to provide a full _expected_ answer. Well, I'm not a mind reader.

    Anyway, visiting the campus and talking to engineers was a great experience. It was worth it.
