it is generally not considered reasonable or appropriate to ask a prospective employee to pick up the tab for a lunch interview. In most professional settings, the employer or the interviewer is expected to cover the expenses associated with conducting an interview.
Asking a candidate to pay for their own lunch during an interview can send a negative message about the company's culture and may create an uncomfortable or awkward situation. It could also potentially be seen as disrespectful or insensitive, as the candidate may already be investing time and effort in attending the interview.
Companies usually view interviews as an opportunity for them to evaluate a candidate's fit for the role and for the candidate to assess the company's culture and values. Therefore, the costs associated with the interview process are typically borne by the company.
If the company is facing financial constraints or has a specific reason for not covering the expenses, it would be better to communicate this upfront to the candidate before the interview is scheduled. In such cases, alternative arrangements can be made, such as a virtual interview or a more casual setting where both parties cover their own expenses.
It's essential for companies to treat candidates with respect and professionalism throughout the hiring process, and that includes handling any costs associated with interviews. However, keep in mind that social norms and practices may vary across different regions and industries, so it's always a good idea to be aware of local customs when conducting interviews.
