Walgreens Customer Service Associate interview questions

Applied online and then completed the in-store assessment 2 weeks later. The same day of the assessment, I got called back for an interview the following day. Interview was very casual, just asked some basic questions.

New ATS (applicant tracking system)/hiring system, so the process took longer than expected. Called in for an interview, position described in detail (including required evening/weekend availability), asked very basic questions, was offered a position on the spot (this location was also understaffed, so this may not be typical), contingent upon successful background check and drug screening. Was sent email to accept the offer (drug screening needed to be completed within 48 hours of accepting); due to the new system, I had to schedule the drug screening, company did not do it. 3-4 days later received a call from management stating drug screen was successful, and was able to start next day.
