Google Technical Leader interview questions

The process is very, very slow. A friend sent my resume in back in January. I talked to three different recruiters during the period from February to May. They had trouble figuring out what groups might be a fit, and, frankly, the first one clearly never did understand what I do. The final group interview request came from a group that I never would have applied to directly (and after I had taken another job). I went simply out of curiosity to see the rest of the Google process. As it turned out, one of the interviewers is someone whose work I've admired a long time, which turned things around. Once I was in the process at the in-person Interview stage, there was a huge improvement in the interaction. I've rated this "negative overall", but it would really be: 4 months negative and 1 month positive.
