    Negative Experience
    Difficult Interview

    Application

    I applied through a recruiter. The process took 4+ weeks. I interviewed at Facebook (Menlo Park, CA) in March 2020.

    Interview

    Network Engineer position in connectivity team. Technical is easy to answer if you have been preparing for interview. Behavioral was tough specially with virtual interview. Interviewer's kid was coming and going between interview. The process toward the interview is great. HR team did a good job from phone screen to onsite interview. At the end I was given feedback that hiring team decided to move with candidate whose background closely align. My question is then why even short list at first place? It takes lot of efforts and time (months) to prepare for FB interview and unfortunately recruiter are not providing right fit to hiring team, eventually candidate suffers.

    Application

    I applied through an employee referral. The process took 2+ months. I interviewed at Facebook (Menlo Park, CA) in December 2019.

    Interview

    Phone screen was easy enough. Made it onsite after many weeks of back and forth (process was unreasonably long). The onsite interview was with all SiteOps folks and not a single network engineering question. Then took almost 3 weeks to get a rejection. Terrible experience.

    Difficult Interview

    Application

    I applied through a recruiter. The process took 3 weeks. I interviewed at Facebook (Menlo Park, CA) in June 2018.

    Interview

    I was contacted by a recruiter and did 3 phone screenings. All 3 screenings went well. After the third one recruiter told me that they won't move forward and gave no reason. I reached out to the recruiter a couple of time to get some feedback or at at least understand what went wrong but the recruiter never responded back.

    I put in the time to prepare for all the interviews and was disappointed that no feedback was provided. I will probably never interview with Facebook again.

    Interview

    Recruiter was unprofessional . She scheduled an appointment and did not show up twice. There was no email apologizing for missing the meeting. She did not follow up for more than a week . I sent her an email reminding her again , when she called she had written script of technical questions to ask . I am not sure how a recruiter will be able to gauge your technical experience.
