I applied in-person. The process took 3 months. I interviewed at Starbucks (Wisley, England) in Apr 2020
Interview
Very little question asked when moving from barista to supervisor position. Most answer to those question are basic day to day question based on barista job and a bit of team management.
Very easy going, most questions were about where coffee comes from and this information is online in the Starbucks website. You don’t need to be an expert of coffee you just need to suggest ways to combine coffee with food.
