I was contacted through LinkedIn by a Google recruiter for their Glasses Team in Google X. I signed an NDA.

I had a short, 30-minute phone screen with an engineer. It was pretty generic, with a few basic questions on RF. Unfortunately, he couldn't answer any questions I had since he was not part of that particular team.

After a month, I was called for an onsite interview. I went to the "secret" Google X building on their campus, though I think some of their teams are spread out in other buildings.

I was interviewed by five people. 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 tenth "we can't talk about that" response.

I am sure they are doing cool stuff, but so is the 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 smarter.

How will you design an oscilloscope? It wasn't difficult in absolute terms, but compared to the rest of the questions, it was.
