SevOne Systems Programmer interview questions

Submitted my resume on SevOne's website and got an email from one of their in-house recruiter about 2 weeks later, offering me a phone interview. I sent my availability via email and waited for almost a month, but still no response. I sent lots of emails to to the recruiter, but I cannot get any reply. This is so confusing, and rude to me. And then suddenly I got an email telling me to take a C++ online test, and I finished it very quickly. And I'm still waiting for SevOne to reply.

Received a call from recruiter and was invited to join Sevone Career Day. We were asked to take a skill test on C and join an interview process. The test is pretty easy.
