I applied online for a position. A recruiter contacted me and asked for my availability for an interview, then stopped responding for about a week. I then received an email offering a time slot for the following day; an hour later, I received a second email stating that he'd actually previously scheduled me for a different time slot and simply hadn't informed me. I did not receive a phone call at the scheduled time. I reached out to the recruiter and found that the interviewer had been double booked and he would not be interviewing me. I was rescheduled to interview with someone else. I did not receive a call at the scheduled time for the second interview. I got in touch with the recruiter again; this time, he managed to find the interviewer and get things sorted out, and we started the interview about half an hour late. The interview focused entirely on SQL and database design, which was a surprise since the position had stressed object-oriented programming and my discussions with the recruiter had stated that I would be interviewed in C# and/or language agnostic questions. When I brought this up, the interviewer was very dismissive/unconcerned.
