After third interview on Friday: "I'll send a contract this afternoon, let me know what you think and when you can start". "Great, looking forward to starting!"

Next Monday: "Oh sorry, no".

But by then I had already quit. As I said, perhaps not the smartest move, but I hated it so much and I feel a lot happier since I quit, so shrug. It's all good; no hard feelings. These things happen.

Also, should be pointed out I didn't reply to a job vacancy, but applied via an "open solicitation" through a connection. So they weren't specifically looking for someone to fill a specific role, and it was more "hey, this looks like a good developer I heard good stories about, so let's talk!"
