Hexagon interview questions

3 Interviews: 1st interview with Recruiter - just the usual where they make sure you are interested in the position. 2nd interview with Hiring manager and 1 senior member - I talked about my background and what I worked on and not to hard. They told me they liked me and the next step would be a panel interview and presentation. the presentation was a topic that I chose and they requested that I keep it simple and not much technical contents. 3rd interview - we started with presentation and right away, the sales guy was asking me questions and asked why my presentation wasn't technical. He jumped all over the place and I answered most of the question. but I felt like I was no longer a candidate for the position.
