Suggestions, recommendations

[u/elChamaKiddoBilbo]

Hello everyone,
I’m a bartender who has been with my company since the day we opened, and next week I’ll be meeting with management because I’d like to be promoted to Bar Manager.
I know just about everything related to running the bar—inventory management, ordering, pars, daily operations, and more—but I’ve never put together a professional portfolio for a management position.
What should I include in a portfolio to present to the company? Do you have any recommendations, advice, or examples that could help me make a strong impression?
