Google Software Developer interview questions

The interviews were with 4 different Software Engineers. From what I gathered online and from the feedback I got from friends currently Software Engineers at Google, I though I had decent chances: strong knowledge of at least one current language, some knowledge about algorithms and data-structures as well as Big O notation. I was surprised to be asked non software questions like various network speed efficiency of various wireless technologies, solve math brainteaser in a language I specifically said I had not used in years, and being told that the code had to compile and run as is, regardless of potential typos. It took several weeks for Google to come back to me but I got a quick offer from a competitor with a more realistic interview process. I'm glad I did not hold my breath, I think I should have left after the second person, it was pretty obvious the process was a plain waste of time.
