Mayo Clinic Associate Engineer interview questions

Contacted in mid April by hiring managers regarding the Associate Engineer position in the SPPDG in Rochester, MN. Phone interview scheduled for May 10th. Notified that I made it to the second round (on-site) interview on May 18th. Second round interview scheduled for May 30th. Interview was approximately 4 hours long with different panel interviews & discussions. I had to give a 30 minute technical presentation on a topic of my choosing. I was contacted on June 22, 2018 by the director of the group with a job offer. Interview consisted of behavioral questions and technical discussion with the director throughout the panel interview. Had a great experience with all individuals involved.
