Eaton Software Developer Intern interview questions

I spent approx. 15 minutes on a call with the Human Resources person. He seemed impressed with my skills and decided to schedule another call with him and the Sales Manager. After rearranging my day to be available for the second call, it never happened. After waiting 10 minutes for him to call, I rang his line and there was no answer. I contacted the operator to have him paged and he was out of the office. I left a voice message asking if call was being rescheduled. He called me back a few hours later saying he would have to reschedule. We rescheduled. This time I emailed to confirm the call 24 hours in advance and it was confirmed. Again, I got no call after rearranging my work day again to take the call. I did not bother to call nor email again.
