Analyst Interview

Washington, DC

The process took 6+ weeks - interviewed at in December 2009.

Interview Details – Phone screen by HR. Then phone screen by hiring managers. In person interview was about 3 hours and 6 different people. Two gave me a series of IQ like questions. Most people were from the analysis group, but one or two from sales and another group. The salesy strategy guy was not very nice, but I think that was just the role he was playing during the interview.

Interview Question – What do you think are the biggest opportunities for this company   Answer Question

Reason for Declining – Too much baggage with that company and no clear growth path.

Very Difficult Interview

Project Management Interview

Project Management
Mountain View, CA

I applied online and the process took 1 week - interviewed at in July 2007.

Interview Details – The phone interview with HR went very well. The person was polite, professional, and asked the right questions. I then had another phone interview with the hiring manager. That interviewer was professional and respectful and asked questions relevant to the position. But when I went for an in-person interview, which consisted of 4 sequential interviews, each interviewer was worse than the last. The 4th was an engineer who seemed intent on treating me in a way which was both degrading and insulting. I was put off with myself for even staying through this disrespectful process. I was asked questions completely outside the realm of the position for which I was interviewing. HR was aware that the candidates were being mistreated, but seemed unable to put a stop to it.

Software Engineer Internship Interview

Software Engineer Internship

I applied through college or university and the process took a day - interviewed at in April 2011.

Interview Details – Very nice workplace. Used to be the old Google building, and it seems to have been remodeled. Interview consisted of four parts, each about an hour long. First asked me about what I would like from the internship and my past coding experience. Then it moved on into a white-board coding/C++ question. After this a different person came in and tested my C++ knowledge. Then there was a one-hour paper test (more coding questions) and then one more interviewer came in for another white-board question. Some of the questions were not so much about coding, but tested your problem-solving abilities and probability intuition. I was really impressed with the difficulty of the interview questions and the intelligence of the interviewers which is largely what led me to accept the offer. I did not expect such rigor from a company I had thought was all but dead, but it turns out that is one of the only things going right for AOL, so don't identify them with one another!

Interview Question – Question that was basically the STL implementation of strcpy.   Answer Question
