Workfall NET Developer interview questions

There were two technical interviews (this is my second application). The process went well but somehow I was rejected a second time. The frustrating part is that you NEVER get feedback. I followed application processes for other companies and they went well, and for those cases where I failed, I got feedback or at least what could be the seniority they think I have. Next try in 6 month but I will not take it. Suggestion? Be kind and give at least a minimum of feedback.
