Anyone can talk a good game in an interview. Someone with zero restaurant experience can say all the right things about being a team player and hustling hard. The only way to actually know if a candidate can do the job is to watch them do the job. That is what a working interview, or trial shift, is for.
Here is the problem with relying on interviews alone. You are hiring based on a fifteen minute conversation in a dining room before open, when the person is on their best behavior and has rehearsed answers to your questions. You find out what they actually do on a Saturday night three weeks later, after you have already trained them, put them on the schedule, and told the rest of the team they are the new hire. By then it is expensive to be wrong.
A trial shift flips that. You pay the candidate for two to four hours of real work during an actual shift, shadowing or running a small section, and you watch how they move. This is legal in most states as long as you pay at least minimum wage for the hours worked. Check your state labor rules before you start doing this regularly, but in most places a paid trial shift is completely standard and protects you from wage claims.
What to actually watch for. Do not just ask "how did they do." Give your shift lead or trainer three or four specific things to score:
Did they ask questions when they did not know something, or did they guess and hope. Guessing under pressure is a server who tells a table something wrong or a cook who plates something off spec because they did not want to look lost.
How did they treat the dish pit, the host, and the new person on the line. This tells you more about who they really are than anything they say in an interview. Candidates who are warm to the manager and cold to support staff are showing you exactly how they will treat your team once they are comfortable.
Did their pace hold up in the second hour or did it fall off. First twenty minutes of adrenaline tells you nothing. Watch hour two.
Did they clean as they went, or did they leave a mess for someone else. This one predicts more about long term fit than almost anything else on this list.
How to set it up without disrupting service. Pick a shift that is busy enough to be a real test but not your hardest push of the week. Assign one specific trainer to own the candidate for those hours, not the whole team. Tell the candidate up front what the shift covers, how long it runs, and what you are paying them. Be clear that this is a paid trial, not free labor, and put it in writing.
Debrief immediately after, while it is fresh. Ask your trainer three questions: would you want this person on your section next to you, did they pick things up at a normal pace, and was there anything that worried you. If the trainer hesitates on any of those, that is your answer. Do not talk yourself into a maybe.
Use it to filter earlier in the process, not later. A lot of operators run the trial shift as the very last step before an offer. Flip it. If you have a stack of candidates for one line cook position, do short paid trials with your top two or three before you commit to a full onboarding and training cycle with just one. It costs you a couple hours of wages to find out for certain instead of guessing and eating a bad hire's training cost, uniform, and the morale hit on the team that trained them.
Document what you saw. Whatever candidate you pick, keep the notes from the trial shift. They become your baseline for the first thirty days. If a new hire looked sharp on trial day and slips two weeks in, that gap tells you something about training or about a manager not holding the line, not just about the person.
This is also where the first week of employment matters as much as the trial shift itself. A strong trial hire can still fade fast if nobody is checking in on them, correcting small habits early, or giving them clear daily expectations. Wingman gives new hires a structured daily checklist and gives managers a simple way to see who is hitting standards and who is falling behind, starting on day one instead of thirty days in when it is harder to fix.
