I applied online and scheduled an online HackerRank technical screen. The interviewer called on time and was very nice. We talked about my resume and about an internship I had. Then, he gave me a search array problem. I solved it in O(n) time, which was what he was looking for. The next day, I received an email to schedule an onsite interview.

Onsite Interview:

1. First round, a 1-on-1 with a developer. He was very nice and friendly. I was able to solve five problems in the first round, which I think is very good. I believe he was very satisfied with my answers. Two of the problems I had seen before, so they required no thinking.

2. Second round, a 2-on-1. The first developer presented a design question based on a project on my resume. The second developer asked me to rank runtimes from smallest to greatest. I got it right in one try. Then, he gave me a dynamic programming question. I found a solution and thought he was satisfied with my answer.

Everything was done in pencil and paper.

I never got past round 2 and was escorted out. I don't even know why; I gave all the correct answers.

I guess it all depends on luck whether or not the interviewers like you.

algorithms, data structures, design

run time, searches, dynamic programming
