Interviewed Aug 2011 in San Bruno, CA (took 6+ weeks)

Started off with a phone interview. I did not hear back for about 3 weeks so I thought they were not interested but then the interviewer called back and scheduled a 2nd phone interview. That went well and they called me in for an on-site-interview. Their campus is really nice and they give free breakfast and lunch. On-site interviewers were professional except one of them. He jumped to technical questions without even introducing himself or asking me about my background.

Interviewed May 2010 in San Bruno, CA (took 4+ weeks)

A Youtube recruiter somehow obtained my resume and called me up to schedule a phone interview. The phone interview went quite smoothly - it consisted of a few background questions, some broad technical questions, and some more specific programming questions. For the last part, we used a shared GoogleDoc, such that I was able to type out my answers.

I was flown out to the Youtube campus (they paid) and put up in a really nice hotel with a group of ~30 total candidates (for what it's worth, 90% of these were graduate students). We had a day-long group tour, including four 1-on-1 interviews, finishing with a dinner at a 5-star hotel restaurant.

The 1-on-1 interviews all had at least one technical question, but the rest of the content varied depending on the interviewer. Some asked questions about spam prevention, others about memory allocation. There were no questions like "how many pennies can you stack end-to-end to the moon?"

It's been almost a year, so I can't remember too many specific questions.

Interview Questions

Implement a malloc-like function such that it only returns pointers evenly divisible by N (presumably some power of 2). Use as little overhead as possible. Implement the corresponding free() function.

Answer Question

Solve Youtube's comment-spam question.

Answer Question

Rather straight-forward bucket sort question.

Answer Question

Rather straight-forward hash question, touching on complexity, hash function distribution, etc.

Answer Question

Garbage collection
