Slower interview questions

You are ask about what is a compiler. Then you present some code/project that you have at home. They indicate you that you will receive an offer. Then they forget about you.

Interviews stretched out over a month. They kept rescheduling at the last minute and the boss couldn't remember previous conversations nor what he previously promised for the next interview. He kept saying he would have a lead dev do the next interview but it was always just him showing up and talking. He was hostile most interviews.
