I reached the final interview. One of the interviewers was not interested in the interview or what I was doing. She asked me to finish writing the code and then just talk about it.

I did what she said and got the answer. I started explaining the solution, and she said she thinks it's okay and I don't have to explain.

I asked her if she had any follow-up questions on the solution, but she said she doesn't.

I ended up not getting the offer. However, I got another offer from Amazon one month later.

Similar to the "Course Schedule" question on LeetCode.
