It was a tough interview to be expected of at Google. The interview process itself was to be expected. It was a standard interview. It was an interview at Google.

I interviewed for the position of embedded s/w engineer. The process is unnecessarily long and consisted of an hour long initial phone interview with HR, hour long on-line coding test and phone interview with a s/w engineer. After "passing" the coding test you will be asked to solve a programming assignment and email them a zip file with your solution, Makefiles and short write up. This takes at least a few days. Passing this gets you invited to the day long on-site interview where you have to answer technical and programming questions.
