Application Details

I applied through college or university – interviewed at BlackRock in February 2013.

Interview Details

The process consisted on one on-campus interview, followed by the superday. The on-campus interview was a normal technical programming interview, consisting one one question. They got back to me inviting me to the super-day after a week. The super-day is pretty intense , consists of 4 back-to-back 45 minute interviews. The interviews are completely technical. Mostly Java/C++ questions testing the concepts of each language and algorithm questions. Hiring process is pretty long, and they took more than two weeks to get back.

    Application Details

    I applied through college or university. The process took a dayinterviewed at BlackRock in February 2010.

    Interview Details

    Got the interview call from the on campus career center. This was a screener for the second interview on-campus in NYC. BlackRock is known to be selective and it surely is so.
    The interviewer started asking me what my favourite subject was, and then gave me a problem to code.
    He gave me a N*N matrix with boolean 0's and 1's. 1's meant that you are "not stuck" and 0 meant you can not move further. after starting from a random 1 position in the matrix, the idea is to traverse the matrix until you encounter an edge with a 1.
    The problem involved use of a good backtracking algorithm to go back to the starting point and find another route in case you get "stuck" while searching for a 1.
    they interviewed 13 people and put 1 or 2 guys on hold, rejected or did not give a reply to all the others.
    hope this helps.

    Interview Questions
    • They asked me to code the algorithm i proposed in 10 mins. i asked all others who interviewed with him and they all said he did not seem happy with the answer. I guess they have a lot of expectations.   View Answer
