QA/Development Engineer Interview

Anonymous Interview Candidate  in  Redwood City, CA
Anonymous Interview Candidate in Redwood City, CA
Application Details

I applied through college or university. The process took 3 weeks - interviewed at Informatica in October 2012.

Interview Details

Met Informatica at the Eecs Career Fair and was contacted shortly after by the recruiter for campus interview. Interviewer was not interested much in my resume. Immediately they started firing technical questions at me. Some on data structures, some on concurrency, and locks. Made it through the campus interview and was contacted after about a week and a half for an on-site interview in Redwood City. Recruiter replied very slowly about the details of the on-site interview. Eventually was contacted by someone else to schedule it. The on-site interview was even more technical. The questions are not too bad, but there are just a lot. By the end of the four 1-hr interviews, I got a headache. Treated me to lunch. It seemed like a very nice company, nice people. But definitely one of the most difficult interviews I have had.
