SAS Full Stack Engineer interview questions

Initial 30 minute phone screen with HR rep, lightly technical in nature. Follow up call with hiring manager, approximately 30 minutes, primarily discussion about role specifics and resume. Follow up technical interview by telephone, one hour in length. Finally, on-site technical interview consisting of a one hour whiteboard session with the hiring manager, a half-hour technical discussion with a manager one level up from the hiring manager, an approximately 20 minute presentation on a topic of my choosing, and closed with a 30-ish minute discussion with HR rep about benefits at SAS. Radio silence for about a week and a half. I reached out for an update, and was informed via email that I was no longer being considered for the role.
