I had two interviews for this position. The first one was at the Siemens office in Houston and the second one was at the San Antonio location. I was interviewed by two people during my first interview. One guy was the engineering supervisor and the other guy was an experienced individual. The second time, four people interviewed me. This interview consisted of the same engineering supervisor and 3 other engineers that worked there. I was a little nervous but they were nice and so I was comfortable.
