Yahoo visited my university for a tech talk. Approximately a month after submitting my application, I was finally set up for a single phone interview. The interview was one hour long, and the interviewer was very pleasant to speak with.

After three minutes of speaking about one of the experiences on my resume, we began the algorithmic questions. After I devised and wrote my solution for each problem, there was a follow-up question about where the solution might fail and require modification (e.g., in a multi-threaded system).

These questions, while seemingly benign, were used to indirectly test my computer systems knowledge.

Unfortunately, Yahoo's interview process seems quite slow.

A few resume experience questions:

Recursion

Indirectly judging computer systems knowledge.
