DBRS - Commercial Mortgage Backed Security Analyst - Intern

I initially met the company at a campus recruiting event. I was then called in for an on campus interview. This interview went well and I stayed in contact with the company, exchanging emails for a couple weeks. They then called me into the office in Chicago, where I underwent the interview process. The process went very smoothly and they majority of questions was about my experience listed on my resume. The toughest question I was asked was, "What is your definition of a Commercial Mortgage Backed Security (CMBS)?"
