I had a basic HR phone interview where they asked me behavioral questions. Then they flew me out to their office in New Jersey where I had a 2:1 interview, which was a bit more challenging and they asked me a few questions on finance. After the interview, however, after following up with them several times, they did not get back to me on the results of the interview. It was only 2 months later that I received an automated email that said "This position is either no longer available or filled," which I found very unprofessional.
