NCR Corporation interview questions

Wonderlic quiz that is basically an aptitude test, must have a clean drivers abstract and a valid G licence. Must know many IT IMAC (Installs, Moves, Adds, Changes) procedures for the job.

It was few rounds of interviews. First with HR, that 3 others with specialist. I got an offer and I gave a call to HR as they suggested. I asked few questions and she agreed to return back with the answers. After 8 days, I received email that since I didn't reply in timely manner they extended offer to another candidate. I asked for explanation and HR lady replied that in voice she sensed I refuse the offer and it was clear signal to her that I don't want this job. I suspect it was bad intentions and I noticed she left NCR soon after this incident. For reputable company like NCR this is very shameful.
