Amazon Sr. Software Engineer interview questions

First phone call interview. General background checking topic. Talked about working experiences, major languages, job role. Talked about what you did in recent projects. Why you want to take this job.

I was contacted by Amazon recruiter over the email for their hiring event in New York City. I applied at Amazon before and recruiter came across to my profile in their database. After sharing my updated resume, I was informed that my profile has been selected to move forward. Next I received an email invitation to participate in an ‘online technical challenge’. It was 90 minutes coding challenge and I had to solve two coding problems. I was able to solve the first problem successfully but run short on time to complete the second one.
