Dynamic Risk Indicator interview questions

I was approached via LinkedIn by a recruiter from DRI about this role, which was certainly of interest. I had a telephone interview with him the day after, which went really well. I mentioned that I was at the second stage with another application, so we agreed to do a phone interview with the Head of Marketing the next day. This also seemed to go ok, but I never heard anything back after that. I messaged the recruiter twice in the weeks afterwards, but despite having instigated the original contact, he apparently had no interest in communicating any further. I could see that he saw my messages, but they were ignored. Clearly I hadn't reached the next stage, but I think it's appalling that he couldn't find the time to reply and let me know. It certainly reflects very badly on DRI as a company to have a member of staff showing this little respect for someone he had tried to recruit.
