Very informal. I suppose it will differ by site. Mostly concerned availability and any past research experience. I found my interviewer to be very easy going and enjoyed the process.
Interview questions [1]
Question 1
Do you have experience tracking and maintaining Balance on Hand (BoH) metrics for retail goods?
Basically making sure you're mentally functional. They will have you come in and they will talk to you about your customer service experience. Having some is nice, but none is required, especially if you handle yourself well in front of the manager. CVS will not bring you in unless they are almost certain they will hire you if you check out.
I applied online. The process took 1 week. I interviewed at CVS Health

Quick 30 mins. Questions were the usual basic ones every job asks. They take you to the back room and into the lunch room and you are interviewed by the manager and their assistant.

I applied online. Got an interview within 2-3 weeks. Got hired the next 2 days. It was a very laid back interview and more conversation like. The manager looked at my resume and asked me about my customer service experience.
