RIA Solutions Group interview questions

I interviewed for a .NET Developer position and went through two stages: an initial HR screening followed by a technical interview. The technical round included both basic and advanced .NET and C# questions, along with scenarios about real-world problem solving. The interviewers seemed professional during the call, but after the interview I never received any feedback or follow-up, despite being told I would hear back within a week. Unfortunately, the company stopped replying entirely and ghosted me, which felt unprofessional and disappointing.
