Google Software Engineer(Internship) interview questions

After applying online google contacted me to complete a few different tests and surveys. A couple weeks later they contact me again to setup a couple interviews. I ended up being interviewed by 2 different people from 2 completely different parts of google in 2 separate interviews. Each technical interview took about 30 minutes and they were strict on time. In the 2nd phone interview our connection was very bad and we could barely understand each other.
