I had an initial phone screening from HR after I applied for the position. Then a phone interview was setup 2 weeks later; that interview was conducted by the department manager and a project manager. It was simply review of my work experience and to gauge my interest in the position. The panel interview was about a month later due to uncertainty of budget availability. This interview was more detailed in the types of questions. I was asked specific railroad knowledge from my previous job and the interview panel consisted of the 2 people from the phone interview and one more project manager....all of which had substantial railroad experience. Overall, it was a laidback experience. The office culture was mostly "baby-boomers" and young engineers with 2 years or less experience. There was a big gap in technical knowledge and experience. Very friendly group of people but that friendliness turned into intense stress during submittal time.
