I applied online and was give a call by a lovely HR lady in couple of days to schedule phone interview. That went very well. You just need to be open, cheerful, don't pause for too long and elaborate on your answers. Few days later I was called for in person interview. Two HRs I spoketo were amazingly pleasant people. Simple open ended questions "how you dealt with difficult customers", "how would yo ex-manager describe you", "tell me about time you had conflicts with coworkers". Smile, be outgoing, make couple of jokes, thank them for giving you a chance. Just be overall NICE and CONFIDENT. Make a point how you always wanted to be in pharmacy business and stress it (this is very true for me). Make sure to ask THEM questions, I think if you don't have any, it shows your lack of interest. I WANT to wok there very very much, so I had tons. 3 days later I got a call - I am hired.
I want to note that I have no college education, certification or pharmacy work experience.
