I had an unpleasant interview with HR/Recruitment where I felt like I was interrogated about the company. The person who interviewed me was unprofessional and tried to give me a feedback on my knowledge about the company, saying she had no time to lose because I was obviously unprepared. Most of the things I was saying to that person were misunderstood by her. The interview ended suddenly because the person got frustrated and didn't want to continue. I got confused because normally the company should be presented to the candidate not the other way around.
