HR contacted me via LinkedIn. Interview was scheduled and I literally had to to wait 2 hours because interviewer was busy with someone else. I was a bit angry at HR for not scheduling at proper time and told them I dont wanna interview but they insisted to wait for some time. I waited. After waiting for around 2 hours, interview started and I was given a problem which I solved. Everything was right yet they didn't offer me a position without any feedback. I even asked them for a feedback but no reply.
