Amazon Software Developer Engineer II interview questions

Contacted my a recruiter and asked to submit a resume and prepare for online code test. Submitted resume and completed code test. Did phone screening. Felt I did really well during behavioral questions. Then got to code test. The coding problem wasn't difficult, but I was not able to figure out the answer without a lot of hints. I could tell the screener really wanted me to do well with the coding problem. I wasn't able to finish the coding problem in the time required. Got contacted by the recruiter that I was getting passed over for the position.
