Great OP! To contribute, since you didn't explicitly mention case interviews, here's a quick write-up:

—Case Questions—
Purpose: These interviews are often used for jobs that contain a lot of strategic problem-solving (anything related to blue-sky type strategy). The interviewer will want to see how you are structuring a problem, how you are accounting for variables, and how you present a solution, all under time pressure. They will also want to see if you are good at finding missing pieces of information. A good case interview doesn't necessarily have a single right answer, it is more a probe of a candidate's thought process.
How to successfully navigate a case interview: Personally, I think these are the most difficult interviews. You will want to start by listening as the case is presented and taking notes of important details. When the interviewer is done presenting the case, repeat back what the final goal is to confirm, and ask any broad clarifying questions. Now, structure the problem. Use some sort of framework to guide additional probes for details, and examine one branch of your framework at a time. For example, if you are trying to understand why a company is not profitable, go into costs and revenues separately. After you've gone down all the branches, prioritize your biggest conclusions, and present them back in an organized manner, making sure to make a point. Throughout this process, manage your time wisely.

I've heard of interviews in technical fields using some oddball questions and/or brain teasers to see how candidates work through problems. For example, "How many barbers are there in Chicago?"

Now, in an engineering firm, these questions would be VERY important and much more revealing than other types of questions. They want to see how you think and work your way through a problem that you don't know the answer to.

You could answer the barber question like this:
1. Find total population in Chicago.
2. Divide in half to get number of men. Women don't go to barbers.
3. Multiply by some percentage to eliminate those men who cut their own hair or don't have any.
4. Figure how many haircuts a barber can give in a day.
5. Figure how often the average man gets a haircut.
6. Describe a rough formula to calculate the required number of barbers.

Or you could answer it like this:
"More than I could count! LOL"

In this case the "oddball" question is really a Competency question in disguise. Would you agree? What do you think of questions like this? With so many jobs being in technical fields, especially jobs that goons are applying for, this could be a common thing.

Thanks, this thread is awesome!

Can't speak to engineering, but in consulting, we call these "sizing" questions. They're kind of a mini version of the case question type.

Question to those with a lot of experience with case questions though, because I still can't see them being as effective at making good hires as behavioral questions; if someone blows the rest of the interview out of the waste but craps out entirely on the case questions, in everyone's experience, what are their chances of being hired?

0%, for strategy consulting firms and corporate strategy groups that rely on cases.

edit: Getting the "wrong" answer or no answer on a case isn't necessarily blowing it. Showing structure, time management, and problem-solving technique, even if it sends you in the wrong direction, is what the case is about. I think they're actually extremely effective interview questions, because they directly correlate to the kind of work done in the groups that use them. Plus, they're kind of fun!
