It sounds like your interview went smoothly and with a friendly vibe! If you want to expand on this, you could share more specific details about your responses and how you handled each question. For instance, you could explain how you described your availability—whether you mentioned flexibility, set hours, or specific scheduling preferences. For the customer service experience, you might want to highlight any relevant roles or situations where you demonstrated excellent communication or problem-solving skills. Additionally, you could elaborate on how you reassured the manager of your capability to handle cash—perhaps by referencing any previous experience working with cash registers or transactions, or by sharing how you stay organized and focused when managing money. The fact that it felt casual is also a positive sign, as it might indicate a relaxed and approachable work environment. You could also mention any positive personal impressions you got about the company or team based on the tone of the interview.
