Signs that I should pass up on a project offer. This was a phone interview by the lead perl developer of $company.
1) He asked for a phone interview at 9:30pm (local timezone for both of us).
2) "We don't have funding for the project yet, but I'll know in the next two days. Can I interview you on Saturday?"
3) "We want to have this done in four weeks. How many hours are you available between now and then?"
4) $company was so secret he couldn't tell me the industry or size, "but it was big".
5) "how old are you?" (this interview question is still illegal in US and Canada).
At this point, I know I don't want the project, but maybe I knew somebody to recommend to him who likes this sort of atmosphere. Then comes:
6) "I'm thinking this could be a project for 3 people. But I might add a few more people if it looks like it isn't going fast enough."
As quickly and politely as I could, I removed myself from the conversation.
