I have interviewed twice at Google now and it seems pretty par for the course. They didn't tell me the interview date and time until the day before, and despite having to rearrange my schedule on short notice, they couldn't have the courtesy of being on time.

After showing up to the call half hour late, we got started. My interviewer was quite verbally irate when I asked clarifying questions and had some connection problems. Then he asked me to explain my code over the phone, brace-by-brace, colon by colon. I asked to share a document it was declined, I asked if we could talk about the algorithm and pseudo-code, but he wanted the C++. Afterwards he told me it wouldn't compile because it was missing some semicolons.

A few months later I tried again, thinking it was a fluke. Second interview started much the same as the first. I just hung up, not worth my time.
