  1. IT Support Technician Interview

    Negative Experience
    Average Interview

    I applied online. I interviewed at CoreSite (San Jose, CA)


    First question was: What will you do if you don't get the job?

    Felt very weird after that and seemed like they already made a choice before the interview.

    If you still work there, you're a terrible interviewer. DOTA 2 sucks btw.

    What will you do if you don't get the job?
