Dutchie POS

Hey yall! I was wondering if anybody had any training aids or info on Dutchie POS. I have a background in IT but have not had the pleasure of working with POS devices and the Dutchie platform. I have round two of a job interview tomorrow (not saying the company) where I’ll be the IT guy for the entire store(s). Also if anyone has info on METRC that would be cool too. Not sure if I’ll be messing with that but I know it’s used to track and would at least like to have a basic understanding. Thanks in advance!
