Amazon Software Development Engineer Intern interview questions

went through two phone interviews,

I applied twice, once in early October and once in late October, and I talked to them at a career fair in between those two dates. I did not get an email until the night of December 3rd, which invited me to interview on December 5th. Usually companies will invite you to choose a specific date that fit your schedule so I found it a little rude for them to schedule an interview less than 48 hours away. Luckily I was free at that time, but I did not have a positive image of the process. The two interviews were going to be back to back 45 min phone interviews that started on the hour, so 15 min break in between. The first interviewer was very friendly and easy to talk to. There was a small chat about my resume and the technical question (through collabedit) was to write a function that takes in an int and returns a string that would be how one would say that number (ex: 123 -> one hundred twenty three; 50019 -> five thousand nineteen). At the end I asked her a couple questions about her work and then prepared myself for the next interview. The second interviewer was even friendlier and nicer and asked more conceptual questions, but they were much easier than I expected. First question was tell me what you know about recursion. Then he asked me to code a function that returned the max integer in an array (no joke). Then a couple questions on sorting algorithms and how I would keep track of duplicates in an array, and how I would keep track of the indeces of duplicates in an array (hashset, hashmap). Side note: the interviewers will take screenshots of your code as you type to track your progress. After the interviews, I heard back 2.5 weeks later saying I had gotten the offer. I believe the your interviewers are from the teams that you are interviewing for. Overall, I was happy with my interviews, but very displeased with the recruiters. My recruiter still takes forever to respond to my emails.
