2 Rounds of interviews. First is basic .NET things and maybe some SOLID thrown in. Second round is the Power Day Interview that they have slotted for 3 hours. You get asked a more algorithmic questions, and then asked to design a system and optimize it, then behavioral questions. Seemed somewhat practical as opposed to just "leetcode" style. I describe myself as mid level, learning about system design currently so of course it was harder and I was a little clueless at some points.
