The recruiter contacted me through a referral. We had a interview where she asked me mostly about myself. Then she told me she would set up another interview through a platform called Karat. My second interview was with an engineer from Karat. He was really nice, we talked a little bit about or previous experience and then he gave me a programming exercise which I solved within time. After that I sent an email to the recruiter to let her know that I had finished this interview. She never sent me a reply. Two weeks later my referral told me I had been dropped from the process. I sent another email to the recruiter asking some feedback but she didn't sent me a reply either. It was a useless experience and a waste of time for me and the company.
