Well after talking to their recruiter I'll set up for a technical interview. The technical interview was actually surprisingly simple conceptually. I was expecting something really difficult maybe a hard algorithm or something but it was just a multi-value dictionary. How to implement it is very obvious for any seasoned developer. However the coding environment you have to use is buggy, intellisense didn't work forcing me to pull up the documents for common types. Despite all that I still completed the exercise in the allotted time just off balance from the environment. The information given to me said using documentation was ok but it seems that and perhaps not being at home with the coding environment will get you disqualified.
