It's kind of unfortunate because the process started off strong.

• I had an initial phone call with the recruiter, who was very friendly and helpful in telling me about the team.
• The first coding round interview went well. The interviewer was absolutely great, and I worked through the two coding questions in the allotted time.
• During the second coding round interview, the interviewer was very nice and assured me to relax. However, he wasn't the most helpful in guiding me through the questions.
• The third coding round interview is when things went downhill. Not only was my interview scheduled for 10 PM at night, but there were a lot of misunderstandings due to a language barrier. For the binary tree coding question, I was led to believe the input was an int array because the problem he copied over explicitly used int arrays. It wasn't until much later that he told me the input was just a regular TreeNode, which wasted a lot of my time. He also tried to talk to me in Chinese, though I have never interviewed in Chinese before.

What are some projects you have worked on?
