    Application

    I applied through an employee referral. The process took 4 weeks. I interviewed at Facebook.

    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.
