This interview was a huge letdown. My external recruiter got me the interview. In the first stage, I had a lengthy discussion with the hiring manager, and they communicated how well my background complements the role. They mentioned that of hundreds of applicants, I was the most compelling. For the next stage, they asked me to do a technical screening, and my result was an almost perfect score. After that, I received radio silence for two months. They then emailed a generic rejection letter.

I had an online interview. The question was given me to search an array of integers ordered but shifted right circular. I answered that this was essentially an out of order array, and he asked "how would you normally search this array". I wrote a binary search, and he showed (apparently) that you could modify the search to compensate. I admit I was annoyed by this whole line of problem. I was very interested in this company, and spent the weekend studying the particulars of the driver code the job description wanted, to be ready. Instead I get an insipid and completely useless C programming puzzle to perform. I could have spent the weekend researching how to do C puzzles, or I could have brushed up on actual WORK knowledge. I think I made the right decision and would do that again. These kinds of google interview gotcha puzzles are just annoying and don't test for any skill or knowledge relevant to actual WORK as a programmer.
