      Software Engineer Interview

      22 Oct 2012
      Anonymous interview candidate
      San Francisco, CA
      No offer
      Positive experience
      Difficult interview

      Application

      I applied online. The process took 2 weeks. I interviewed at Quantcast (San Francisco, CA) in Oct 2012

      Interview

      I was contacted by a recruiter within 3 days after applying online, asking me for a first phone call. This call was mostly to present me the position, and also included some questions about my background. It didn't really feel like I was being evaluated. I had to complete some homework (write a simple command line program that performs some calculations on its input). This homework took me about 2 hours of work. After reviewing my solution I was invited for an on site interview. There was 3 interviews, one with an employee from another team, one with an employee of the team I was applying for, and one with a technical lead of that team. All interviews were classical 1:1 technical interviews: - Talk about my background - Some general questions covering topics like systems and network programming, CLI use, and other software general knowledge. - Coding exercise - Open questions and presentation of their jobs The most challenging part was the coding exercise. Focus was on simple algorithmics on arrays and trees. In one of the interview, the language was suggested (C). One of the coding tests was on a variation of binary search which I couldn't get right in at least 40 minutes of interview, despite interviewer trying to help me. This probably cost me the job, together with not fitting exactly in the profile they were looking for. There was no behavioral question, although I feel like After about one week I received a thank you e-mail stating that I was not a good fit.
