Discover interview questions

They sit you down, and basically ask you a series of questions. The individual that interviewed me spent a good 45 minutes with question after question, then proceeded to decline my interview. I called the department manager directly because I felt I was treated unfairly, and the DM agreed with me and proceeded to employ me

I applied for this role through an employee referral and received an email from the HR within 5 days. The HR wanted to know my background, qualifications and salary expectation before scheduling an interview round with the hiring manager. I had to give these answers in the form of an email. After sending the responses, I did not hear back from the recruiter for almost 2 weeks. I emailed her twice to check my application status (whether I've been rejected), but I did not receive any response. After almost 3 months, I got an email from her saying "Thank you for the time you invested in the interview while we are sorry that we have selected someone else for this position" I never gave any "interview", nor did I receive any feedback from the recruiter. It was highly unprofessional on her end to not have a simple ethic of responding to a candidate (when she has emailed a couple of times)
