Draper Radiation Effects Engineer interview questions

Initial call with hiring manager to verify my experience made sense for the role. Scheduled call with large group. Two thirty minute one-on-ones with the hiring manager and a person one tier up. ~40min technical presentation on a topic of your choice. ~Five one-on-ones back to back afterward that varied a lot in the nature of the interviews. Was told I would be extended an offer that day. Offer extended the following week.
