I was told to meet the hiring manager at the first round on-site interview. However, the hiring manager disappeared and the front desk knew nothing about the interview. The recruiter reconnected me with one of the team members, so that I was able to get in. The interview lasted from 9am to maybe 2pm, with only water for refreshment. I was later asked to do a second round of on-site interview, which was the same as the first one, except that the hiring manager appeared at last. Later, I received a rejection from the hiring manager citing a reason that was simply the opposite of what I had said during the interview and written on my resume.
