NCR Corporation interview questions

One interview, was told I would only need to talk about my resume but then 15 minutes in I was hit with two whiteboarding questions. They weren't too difficult, but I was not at all prepared for it.

The process was inline with IT norms Usually the first round is to get idea of how much knowledge you have . Then they schedule a second round with hiring manager which goes in details. The last round if required is with Director. Overall smooth process
