Was first approached by an internal recruiter at Facebook via a LinkedIn message. Within a week I did an initial 15 minute screening interview in which the recruiter asked me if I had experience/competence in SQL, Python, or R. Afterwards I was sent around 2-3 emails containing study material, along with advice on how to prepare for a 1-on-1 video interview I was to have. After I reviewed the material I was to schedule a time to interview with a Data Scientist Manager. The interview was a mix of analytical problem solving and technical. It was enjoyable getting to interact with someone very talented in their skills and showcased Facebook's level of talent well. During the interview there was a degree of guidance as I navigated the technical components and analytical portion of the interview, which was expected per the interview prep material. Personal Analysis of Interview: It was great getting to be challenged both technically and analytically from the top talent around, and felt that I showcased my problem solving capabilities well but undersold my technical skills. Not sure I would have done any studying differently, I am just not at the technical level that is required at a company like Facebook. However, it has been nearly a month since my interview and haven't received any communication from the HR department despite multiple (3) follow up emails on my behalf. Very disappointing, as I had a wonderful experience leading up to that. This experience has definitely soured the experience and desire to work at Facebook. Hopefully this is an isolated case.
