Helbling & Associates interview questions

Initially met two executive recruiters at a career fair at my college. Knowledgeable guys that did a great job selling their company and explaining what they do. Sent my follow up emails and heard back within two days that they wanted to set up an interview. Interviewed with Tom, the CEO. He was a more intimidating interview than I was used to, but I felt that it went well. They said to call back if I was still interested. I gave them a call the next day, and after that conversation, I haven't had contact with them since. There was no official denial, which I always find very unprofessional for a small company. I've received handwritten denial letters from companies much larger than Helbling.
