I applied online and was set up with a phone interview. I was asked to move zeros (LeetCode) in-place and remove duplicates from an array (with many follow-ups).

After that, I was invited for an on-site interview in New York. There were two technical interviews. They began with resume questions, followed by data structure and algorithm questions.

Interview 1:

1. Flatten a singly linked list.

Interview 2:

1. Find all unique triplets that sum up to a target.
2. Given prices for flights to New York and San Francisco for each person, you want to send half to New York and half to San Francisco with the least cost.

Flatten all

Three sum uniques

Optimal flights
