Beware that there is a reason this company is constantly advertising the same (Senior) Systems Engineer positions over and over. Initial phone interview with VP of Operations was a technical self evaluation on technology. 40 hours a week plus time for certification was mentioned. Second interview in person with a Project Manager. Evaluation on all the technology areas you know. Questions were pretty basic. When asked about the hour commitment, 40-50 hours a week plus certification studying on your own time. He personally has no idea how much he works because he enjoys working there. Third interview in person with the owner. 37+ billable hours per week is mentioned which means a consistent 50+ hour work week with all your time spent at client sites. The amount of certifications I had was looked down upon and the goal was to get several difficult certs within a year. Owner is a former Marine who literally runs the company that way.
