Aspen Institute interview questions

I was contacted by hiring manager about a month after I applied to have a first-round interview. The interview was very short, I was only asked a handful of questions, which I found strange. I honestly thought the interview went extremely well other than that. I was comfortable and had well-prepared answers, and the hiring manager seemed to receive them well. I was very shocked to find the rejection email in my inbox after the holidays. I guess you can do everything right and still get rejected.

Applied online. Heard back after 2 weeks. Short 15 minute call with Hiring Manager. Questions covered project management experience, why I wanted to work at a mission-led company, experience of using tools to manage projects, experience of working with people from different backgrounds. Rejection email the following week.
