Interview questions: WPF Developer [closed]

Solution 1:

I'm surprised no one has mentioned basic knowledge of XAML yet. Knowing what XAML is, and the ability to do some basic editing using XAML rather than a graphical design tool. Mid-level developers should be able to knock up form / graphic prototypes using a tool like XAMLPad.

Solution 2:

Personally I would sit them down in front of a standard developer build machine and ask them to complete some task. No questions, just see what their code is like after a couple of hours (or more if the task is longer).

I have had a zero failure rate on making a hiring descision based on the results of an actual real life programming test.

The task doesn't have to be too difficult. I've used a simple message of the day application in the past with the messages being held in a database or XML file and a simple user interface. Ensure you ask them to structure it well (as the task is sufficiently small that it could all be done in one class if they felt inclinded).

Of the questions above I'd say you cannot get a good idea of whether they are really any good or not. A potential candicate could actually just read these and create canned answers that sound great. All this shows is that the candidate can talk-the-talk, but what matters in the job itself is if they can walk-the-walk.
