In an earlier era, job interviews were almost always formal affairs that involved a thirty-minute conversation in an on-site office or conference room setting. Employers would sit down with potential candidates in a clean, quiet professional place free of distractions and ask a series of questions designed to assess the candidate’s readiness for the job at hand.But in the current job search landscape, a new format seems to be on the rise: the lunch interview. There are several reasons why employers may choose to hold an interview over a table at a restaurant or coffee shop instead of an office. In some cases, these employers are start-ups operating on a thin shoestring, and their newly-established or not-yet-furnished office spaces are insufficient for the interview process. In other cases, holding interviews over lunch can save time. Sometimes employers choose a lunch interview in order to observe how the candidate responds to distraction or behaves in a real world setting. In any case, if you’re invited to a job interview that takes place in a restaurant, keep these tips in mind.
