I was contacted by one of their recruiters. Typical HR questions. Then I had an online coding interview - a TDD exercise, and then a behavioral interview with some managers.

3 steps. HR phone call, TDD code kata in c# or relevant languages, technical round with drawing an architectural diagram and questions around that. I nailed the TDD coding round but second round was not went well I realized after knowing the result. HR was very friendly but too slow .. even if you mail don't always expect any reply. It took some time to get the result which was to say go find another job.
