You must apply via the CVS website. Calling to advise your desired location that you've done so is always a good idea. If you are called for an interview, it's a pretty standard procedure, standard questions, like "what is an example of a time you helped a customer with an issue", etc. If hired, you will be subjected to background check, drug test, then classroom training before you are officially onboard. Once you are actually working, you will have many online modules to complete in the first 30 days.
