Had a phone interview. First, I was asked about my resume and my interest. Then, I took a shared-screen coding challenge.

I was asked if it was the most optimal solution. After about two weeks, I was invited for an on-site interview, which consisted of three interviews.

The first was a coding challenge. The second was a behavioral interview with a coding challenge. The last was also a coding challenge.

Usually, people are asked 4-5 coding questions. It depends on the time you have.

Practice medium and hard questions on LeetCode.

I think for phone interviews, you will most likely be asked one hard or two medium questions. For on-site interviews, it's usually easy/medium questions.
