Hiring manager contacted me via LinkedIn profile from which I applied. I got interview with there technical person for screening with questions like tell me about your self, 2 database related questions. And told me that they will reply by end of the week. Now they just ghosted me. Hiring manager do not even have courtesy say no and kept me waiting.

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.
