Resolve Systems Software Engineer interview questions

Apply online and receive two round phone interview, and then the onsite. The bad thing is after the onsite interview, no feedback. Not even send an email to let me know if I failed or not or why.

I went through a phone interview, then an in-person behavioral and technical interview (on the same day), and a post phone interview. Even though the phone interview questioned specific programming language features, the technical interview were white board questions on general problem solving tasks. The technical interview turned into a pleasant discussion between the programmers of the problems being solved at hand. Unfortunately, the end of the process was dragged on for weeks (phone calls after phone calls of planning the final interview, which never lead anywhere) and I never got a decision in the end.
