What is the longest interview process you've been involved with?
The longest, time-wise, has been as a candidate for a contractor position. I'd gone in to one or two interviews, plus a meet and greet with the client. And then it took a while for the position to be funded. And then the department had the money, but it couldn't add it to the contract. And then blah blah blah. It took almost a year to bring me on. (Which was fine because I was on the fence of leaving my current job anyway.)
