WM Technical Support Analyst IV interview questions

I was told by Icon Information Consultants that there was a job position that WM was wanting to fill. I felt that I could do the job, so an interview was scheduled and I went to the 2nd floor of 1021 Main St. I was brought up to the 4th floor for the interview. The person interviewing me told me that I was going to be asked 10 questions and if I did not know the answer that I should say "I do not know". Otherwise, I would rejected on the basis of bluffing an answer. I answered all 10 questions correctly and left back to home. I told the consulting firm of what transpired and the next day I was offered the position. I accepted the income that I was going to make and was pleased that I was able to start immediately getting myself situated with all information that I needed to be successful in my position at WM.
