Was contacted by a recruiter to set up an initial phone interview. At the last minute it was switched to an actual phone interview. I had a lot of questions lined up, but my interviewer wasn't interested in answering those, only stuck to her lengthy list of questions. She was incredibly rude and condescending. I got off the phone thinking, "if this is how they treat potential employees, I'd hate to know how they treat current employees or customers." My personal favorite was when she asked if I was familiar with their competitors. I informed her that I had used DropBox, which is free. She then went into a rant about how they were similar, but in no way related or affiliated with each other. Duh, that's why I listed them as a competitor I was familiar with.
I hope they recognize that the people they are interviewing could possibly be potential clients in the future. I walked away with a bad taste in my mouth.
