I first applied online in January - got rejected by the stupid resume filter system. Then I dropped off my resume during a career fair with one of the recruiters, which lead me to a 30-minute phone interview. Recruiter sounded like he doesn't want to work there at all. I kept hearing audible yawns and sighs every minute while I'm answering his general HR questions related to my resume. This is a junior position and the recruiter said that juniors are not expected to have prior knowledge in languages and skills related to the company's product, but later I got a rejection email saying there are more qualified candidates. I worked as a dev before and now in graduate school for CS, so not sure which skillset was dissatisfying.
