A barista application benefits from evidence of both drink preparation and dependable customer service. The source's sample résumé is useful for identifying categories of experience, but its example identity, address and employment history are not material to reuse. Your application should describe work you actually performed and skills you can demonstrate.
Explain the tasks behind a job title. Relevant examples may include preparing orders accurately, handling a busy counter, cleaning equipment, maintaining stock and communicating with colleagues. If you have used espresso equipment, identify the training or responsibilities involved without presenting casual home brewing as professional employment. Experience in another customer-facing role can still demonstrate useful habits.
Match the résumé to the vacancy and keep the evidence easy to scan. Training, availability and a concise account of relevant responsibilities are more informative than unsupported claims to be a coffee expert. Use real results when you can substantiate them, and leave out invented achievements. A sample document should help organize your own experience; it cannot guarantee a job or replace the employer's assessment of how you work with people and equipment.
The conversation
A good question can make a better brew.
