They asked me to come in for the first round onsite. I provided my schedule, and they arranged the first round with the hiring manager and another software engineer.

Ten minutes before the interview, I received an email stating that the hiring manager was not in the office and would conduct the interview via Zoom from one of their meeting rooms. I was then in a dark room where the manager couldn't even see me. The hiring manager proceeded to ask random questions irrelevant to the role.

For the next round, the engineer arrived 15 minutes late. After that, he asked me a couple of coding questions and a few other technical questions. I was able to solve them and answer most of the questions.

A couple of days later, I received a rejection email. I felt the hiring manager was not at all interested in hiring.

Don't waste your time with a company that doesn't value candidates' time. Why would you call someone onsite if the people interviewing me would not even be onsite?
