Submitted my resume during college career fair, heard back about two months later over email requesting an on campus interview. Two 45 minute interviews each with 1 coding question. First guy was talkative and explained what he does at Amazon, the second guy was straight to business and barely spoke. Both were friendly, just the second interviewer seemed like he did not want to be there. I prepared a lot in the prior weeks using the cracking the coding interview book, but honestly the questions were simpler than expected. My problem was that I misinterpreted the question a few times and tried to over complicate things (the coding interview book had much more difficult questions). It has been a week since the interview and still waiting to hear back.
