I applied online at Xcel.com for a job that read "Engineering Intern- Performance Testing Lab." I received a call from Minneapolis, MN 3 weeks later for a job in Amarillo, TX. That recruiter was from human resources. He set up a telephone interview the next day so that I could interview with a projection engineer by the name of Sean (last name withheld). He used STAR behavioral interview questions. As far as the technical side goes, he asked my level of expertise/skills on thermodynamics and fluid mechanics. He also asked if I had any health issues and if I was afraid of heights in excess of 250ft. He also stated that this job would get your hands dirty as it was in the field. After that, we had a little personal talk about what the job was actually about. He said we would be testing power plants in the northern New Mexico - Texas panhandle area for thermal efficiency and make suggestions as to what measures could be taken in order to increase their efficiency.
