GLG Graduate Associate Programmer interview questions

I applied online and a few days later got an email telling me I got a telephone interview. The interview itself was about 30-40 minutes and was asked plenty of questions, mostly about my background and some behavioural questions. I was told that I would get a response at the end of the week (interview was on a monday). At the end of the week, I did not receive an email. I waited another week and decided to email the recruiter to follow up on how the interview went. It has been almost a month since the interview and the recruiter has yet to answer my email. Rather appalled by the unprofessionalism of the situation, it gives a bad look to the company.
