Note: I applied as a contractor, so maybe their normal process is different.
I did a couple phone interviews, then they had me come in. I talked to a few people, and they all seemed very friendly. At the end, the main guy said they were ready to hire me, and to expect an offer. After that, I didn't hear anything for a while, so I called him. He said he was busy, and that I should sit tight, they had to rearrange some budget, blah, blah, blah. I waited a few more days, and called again. He got really upset that I had called him, said he was a busy guy, didn't have time for this call, and that he'd reach out when the situation changed. I never heard from them again.
