An HR rep emailed me to set up a phone interview for the next day. The interviewer missed the first appointment. After I contacted him, he set up another interview for the following day. He missed that appointment too and finally called about an hour later.

The interview went pretty well and lasted about 40 minutes. At the end of the interview, he told me they were interested in proceeding to the next phase, which would be another phone interview with him, his manager, and possibly an engineer from the team the position was with.

This was three weeks ago, and nothing has happened since then. I have sent several emails and left a few messages on his voicemail, and I haven't gotten any response at all.

None of the questions were that difficult. Mostly, they were just basic questions about my experiences listed on my resume and a few questions about my problem-solving process.
