Quest Software C# .NET Developer for Server Virtualization interview questions

I had 2 phone interviews with Quest Software human resources people. The second phone interview came about one week after the first. In the first phone interview they sprung a .NET test on me. They were constantly telling me to read and understand their website for the interview with them. The website was http://www.vizioncore.com. In the 3rd and final phone interview, a manager asked me questions that lasted for 5 minutes and that wasn't because I didn't have any answers. He only asked 3 questions. No one got back to me for 2 weeks so I emailed one of the HR people. She told me I didn't get the job. I emailed back letting them know that they were unprofessional to not contact me and let me know as they said they would. I don't recommend interviewing with Quest Software or any of its subsidiary companies such as Vizioncore. Very unprofessional!
