Kroll Internship interview questions

Applied online, then was invited to an interview, I drove 3 hours from swansea to an interview. When I arrived the lady who was meant to be carrying out the interview looked surprised to see me and hadn't prepared any questions, In fact I asked her more questions than she asked me! we had a pleasant chat then after 15 minutes I was on my way back to Swansea you can imagine my frustration. I didn't get the job..
