Amazon Software Developer interview questions

The recruiter contacted me through email having found my resume through my university. She allowed me to provide a range of times when I was available over the next few weeks and we scheduled a phone screen interview. 1st phone screen: Interviewer was nice and asked me to turn off my computer and take out a sheet of paper and pen. I was then asked to write some code. Interview went pretty well, and the interviewer helped me out when I got stuck. I was then asked to read the code out to her and was allowed to ask her some questions of my own after the coding portion. I received an email around 3 hours later for a second phone screen.
