Applied online and was invited to a hiring event about a week after the job posting closed. I was notified by e-mail to check my applicant status on the UP website. I was asked to chose a location to attend for the hiring event, which was not very close to where I live. The closest was in San Antonio, TX so I had to drive down from Dallas.
There were 13 candidates at the session. The session began promptly at 8 am with a safety brief from the UP HR rep. There was only one rep at the event, not 3 or 4 as others have mentioned. We began with the Ops Management test which took about 3 hours. The test wasn't too difficult but it wasn't too easy either. After the 45 question analysis/logical reasoning portion the HR rep began interviewing us one by one while we completed the remaining personality profile sections of the test.
We were informed that it would take about a week to find out if we passed the test and that if we were selected for second round interviews we would be flown to either California, Nebraska, or Texas for the interview. Apparently the training class will begin in about 6 weeks so it seems that this is a rather quick process.
There was no offer made at this session because we have to wait to advance to the next round. Overall this was an enjoyable experience.
