I applied online. The process took 1+ week. I interviewed at Walgreens in June 2013
Interview
Applied online, received an email two days later to discuss details of possible employment, went for an interview one week later and got an offer on the spot.
Was able to schedule my interviews quickly and they were very responsive to emails. They asked very basic questions about your background as well as your motivations for applying. The recruiters were very nice and easy to talk to.
There were behavior based interview questions, tell me about yourself, strengths and weaknesses. Usually with a pharmacy and store manager. Maybe with a district manager. A tour is given if interview is in person.
Interview process was really easy - they ask basic questions for any normal pharmacist job and a routine screening. I worked at Walgreens as an intern for most of my college years so there wasn't much additional screening for hiring as a pharmacist.
