Centripetal Networks interview questions

First it should be noted that they continuously post for positions that do not actually appear to be open job reqs so if you're interested in joining this company, keep that in mind. I went through all the steps - phone screen with the hiring manager, an in-office interview with multiple people. This was followed up with yet another phone interview with someone who I would be working with. All interviews seemed to go very well. I was told they would have feedback for me after the final phone interview. That feedback never came despite several attempts on my end. They wasted a lot of my time and a lot of their own time just to end things as unprofessionally as they possibly could. No offer came but based on the lack of professionalism during the interview process, I'm okay with that.

Phone screening was a computer science competency screening. The in person interview was meeting with the technical team, then the management team and then upper management. The hardest interview was the 3-4 data structures and optimization questions by the technical team. The management panel had a lot of problem solving and personality. The upper management was more of a where the company will be in X years and where one would fit into the vision.
