Got contacted thru LinkedIn by a Google recruiter for their Glasses Team in Google X. Signed a NDA. Had a short 30 minute phone scan with an engineer - pretty generic, few basic questions on RF but unfortunately he couldn't answer any questions I had since he was not part of that particular team. After a month, was called for an onsite interview. Went to the "secret" Google X building on their campus (though I think some of their teams are spread out in other buildings). Got interviewed by 5 folks. The level of questions was not that bad and I had the impression that none of them were really well-versed in analog mixed signal RF. Anyhow, they seemed pretty secretive about what they do which was a bit strange especially after the 10th "we can't talk about that" response. I am sure they are doing cool stuff but so is rest of the industry - Apple, Intel, Microsoft, Samsung. Somehow some of their attitudes struck me as being way too elitist and smug as if being in Google X made them magically smarters.
