One of the problems with debugging is that everyone seems to approach it differently. With some of the approaches working better than others in some situations. Which is why a group debugging session works great when you have a tricky problem that is not getting solved by one person.

We can definitely test for basic debugging and troubleshooting skills. But I havent found a way to consistently evaluate people who are capable of identifying and finding solutions to complex problems. These days a lot of these come down to framework level experience. With the proliferation of frameworks and tools used in modern apps, it is impossible to find someone who can solve problems involving all of them. So in a big team you want a variety of such experiences to cover a wider base.

Having said that, I have been in many situations where i have had to join a debugging session involving technologies or programming languages where i have had zero prior knowledge and have moved things towards a solution by asking what at times seems like basic queries to help others come up with the solution.
