Phone Interview with talent coordinator - likable and upfront, he is the gatekeeper. 2nd Interview with owner - will give you a solid feel if you're a good fit for the company. Be yourself. Honesty is paramount. 3rd interview with CTO - Challenging, he really knows his stuff. Be prepared to dive deep on anything on your resume. If you appear unconfident he will ask him you more questions and determine what you know. Difficult interview but fair and enjoyable if you like challenges. This interview actually made me better prepared for future technical interviews.

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.
