Google

I had one online assessment, one phone interview, and four rounds of on-site interviews. The overall process was pleasant. The interviewers were very kind and helpful. Besides that, the food in the cafe was very good.

Easy for geniuses. You have to attend top schools for a position at Google. The salary is high. Party all night, code in the morning. I hate Glassdoor for forcing people to write reviews.

This is a classical "Cracking the Coding Interview" type of interview. It needs a bit of improvement. It is not hard if you work on all those questions on the internet. However, if you don't, it is kind of harder to pass.
