Ascendion NET Developer interview questions

Recruiter randomly calls you, and schedules you for first round interview. In the First round asked a ton of .net and C# questions with a coding interview at the end. 2nd round was some more .net and C# questions with a coding challenge. No call back or email after the 2nd interview... very unprofessional since the recruiter is so desperate to get you in for the interview but they do not have common courtesy to tell you if you did not pass.
