Passed rigorous phone screening and two interviews: * One technical coding assessment. * One focusing on interpersonal skills and past experiences. The people were nice and helpful when you got stuck.

Standard LeetCode gatekeepers. There is nothing special about it. They expect you to solve multiple problems, about three in total. If you manage to solve them, then they will consider you. Experience doesn't matter; your correct answer matters.

It was an easy question, but the interviewer insisted on finding the most optimal solution, which took a lot longer than expected. It could have been done in four lines using brute force. Just practice HackerRank and LeetCode, and don't be nervous.
