I was contacted by a recruiter via email and then followed up with a 20-minute phone interview, where I was asked basic behavioral questions and an overview of positions that fit my experience.

After the phone call, a 1.5-hour coding assessment was sent to me. After completing it, I was invited for an onsite interview. Here is where things went south.

I was greeted by three interviewers who were very rude. They did not ask me any questions about myself; it was purely technical, and they started off the interview with a hard-level LeetCode problem. During the entire interview, they were condescending towards my accomplishments and when I did not know how to answer a question. About halfway through the interview, one of the interviewers muttered something in Mandarin and left the room. Overall, I thought the interviewers were very unprofessional, and I did not feel respected at all.
