My worst interview experience ever.

I had two rounds of phone interviews for general coding questions of medium difficulty, and I did well on them. After the two phone rounds, I was scheduled to interview at SF.

The onsite interview started in the morning. The first round was about discussing a complex coding question. It went well, and the conversation was good.

I rate my interview as my worst interview experience because of the second round. There was a man who said he was a manager. Without much introduction, he started to chat with me. There were no coding questions, but something like knowledge about computer systems. I didn't answer well, and he kept pushing, saying, "Say you don't know if you don't know it."

I think he was the rudest interviewer I have met compared to all other interviewers. I believe he had strong discrimination because of my gender. I am sad that females have a disadvantage in the software engineer role at this company.

I got rejected soon, and I will never recommend this company to any friends.
