I was brought on with the promise of 6-months on-the-job training, so I could get up to speed with the equipment and processes used in field service work. The nature of field service was that you could be called out for emergency repairs - they would not wait until normal business hours. I once drove 6 hours to replace a component, then 6 hours back, so I could perform a scheduled job in my base location the next morning. THEY DON'T PAY ENOUGH, or even competitively for the markets in which they operate. $25/hour is well below market in DFW for field service; don't be fooled. I was also told that I would primarily be working in my immediate region, but spent most of my time driving out of state for 30 minute PM jobs. Be aware, they WILL fire you if a customer has a complaint - regardless of fault.
Per diem; handler/schedulers are professional and courteous
Excessive travel, unplanned (midnight) repair jobs
