First Round Interview was a 30 minute phone interview that was strictly behavior-based. Questions that were asked were straightforward and went something like this... Tell me about a time that you had to work with an unsatisfied customer. It only took them about 1 day to get back to me about scheduling a second round interview.
Second Round Interview was geared more toward the position you were interested in. They asked a lot about your experience and how it could help you as an Intern and Walgreens in general.
