Research and Data Analyst Interview

Anonymous Interview Candidate in San Diego, CA (US)
No Offer

Interview

Interview consisted of giving a technical talk about my previous research to a group of ~15 people, then 3 closed-door meetings one-on-one, first with a potential boss and secondly with two people who would have been peers. After interview, an HR rep told me by email that the feedback had been positive, but I didn't hear anything else back so I guess she was just blowing smoke.

Interview Questions

    Written test consisting of aptitude+Logical reasoning with verbal ability, as like always.
    Short listed students go through 3 one to one interview process. At each level, candidates are short listed and then passed to the next one.
    All interview rounds included puzzles, knowledge about opera, understanding of graphs given by them at that spot and explain it to them. They will surely ask from resume that you put forward.
