He really helped me by telling me the topics and a few questions which the assigned interviewer usually asks.

The interview first ask me to open LEETCODE and gave me a HARD question about STACK - related to bracket question.

He first asked me to write the Pseudo code but I started writing proper code. After a period of time, I got stuck and he gave me a small hint I solved the question then he ask me to submit the code and it submitted successfully. This one question took 40 minutes. He didn't even ask me more questions, also he was yawning and it seemed like he was not interested at all. At the end of the interview, I asked him if he will ask more questions, and he said it is fine it was a hard and lengthy question.

The next day I got the rejection mail.
