I applied online. Three rounds of interview processes: 1) phone screen about 30 min with a hiring team, 2) on-campus interview about 45 min, 3) on site interview. Phone interview was done with one person but on-campus interview was with a panel of 2 people. They were very nice overall

PEH recruits on-campus for this program. After the initial cover letter and resume submission, the first round was a ~30 minute phone interview with 1 committee member. The next round was a 2-member panel interview during their on-campus visit.
