Google Software Engineer interview questions

I got a technical interview after they contacted me via email. The technical questions were about computer science concepts: OOP, data structures, algorithms and optimization.

I applied through their website a few months after graduating, and received a response about two weeks later. They e-mailed me a list of tips and things they'd recommend studying for the interview (hash tables) etc. Interview was done using Google Docs to type out code while talking over the phone. Unfortunately, I should have studied more and did not get the interview, and they recommended waiting at least 12 months before trying again.
