Yeah. I'll never interview with Google again. I've got friends who work in (mostly nontechnical) roles there who had very different experiences, but my interview was such a hot mess of disorganization, cluelessness and arrogance that I ended it early and told them I had no interest in the role or the company.

Two years on, I think I made the right call.

Yeah I had a somewhat similar experience. My first technical interviewer was 15 minutes late (so it was now a 30 minute interview). Then, after being asked the typical slew of questions (what is a hash table, etc) I was asked to implement a basic data structure (Set). Which was easy enough but my interviewer wouldn't let me finish writing up my implementation and, instead, insisted I focused on optimization of a particular, custom method he asked me to implement. I protested (premature optimization, etc) but ultimately went along with it. I finished optimizing but didn't get a chance to finish my Set by the time the interview was over.

I got an email a week later saying thanks but no thanks with zero explanation. I had gotten everything right, what went wrong? So I had some of my Google friends track down the interviewer and ask. Apparently I didn't continue forward because I didn't finish my Set implementation...

I've had Google contact me on occasion since then. I have not re-applied / re-interviewed with them. Their interview process is already bad enough.
