I actually really enjoyed the interview process with Google. It was expeditious and respectful. It was, however, clear they are not used to taking "No" for an answer, and that's when things got a little uncomfortable.
I suspect it may've been because I was hired at the bottom of the 2009 recession, right around when they fired all the temps and all the permanent recruiters were fearful of their jobs and there were virtually no other candidates in the pipeline, while folks who applied in 2007 or 2011-2012 when it was much busier got a terrible experience.
