All electronic. Nothing personal. Timed tests to complete and return. When I questioned them on the phone about something I discovered in the test (an error), they put me on hold, then came back with the wrong answer upon which I was to base my answers. This, in turn, made several of my answers incorrect. Since determination of correct answers was done by a computer, I then had to follow up by phone and once again point out the errors on their part causing the subsequent errors on my part. Talk about wasting time, going in circles and making a bad impression by having to tell them of their error. They don't get back to you with any results so that YOU can learn from what they wanted. Very one sided. Not impressed with their HR.
