Interviewed with 2 managers at first. Got selected for a follow up interview on-site where I had to do a 30 minute presentation on a technical topic of my choosing in front of about 8 people. They then asked me several questions about my experiences and then I sat down with a sales rep to talk more about the job. Very personable interviewers. Very exciting job opportunity. They did a great job of giving you an idea of what it would entail and the corporate culture. My only issue was that they took around 2 months to decide to go with another candidate and then they didn't even notify me or my recruiter. Struck me as rather unprofessional.
