I submitted my resume through the school job fair. The process took four weeks, and then I got a phone interview.

The first-round phone interview was around 45 minutes. We went through my background and previous internship and project experience. They asked about my most interesting project and previous teamwork experience. I was asked three algorithm questions.

1. Combine two sorted lists; ask time complexity.
2. Combine k sorted lists; run an example and explain.
3. Given an iterator of lists, how to combine them.
