Amazon Software Developer interview questions

Two phone interview

I applied to amazon months before until they actually contacted me. Im assuming they do seasonal recruiting since i applied near the summer into fall and i get contacted in the winter. I had 2 phone interviews. Both interviewers were very nice and helped when they thought it was necessary in order for you to succeed. The first phone interview was not difficult if you read all the questions on glassdoor that people posted and read the cracking interview book that somone did suggest in the intervews tab list. The book was extremely helpful. the second interview was majority coding questions and at the end of each coding question the interviewer would ask time complexities. After I ended the phone interview i thought to myself i made like 4 mistakes answering the first question and knew i was doomed from that point on. I received the generic rejection letter one week after the second phone interview. the interview process for me lasted roughly a month because i interviewed right before the christmas vacation
