Dishwasher Interview Questions for Kitchen Managers

This page is for the kitchen manager, chef or restaurant owner hiring a dishwasher, not for candidates. Nobody needs a license to wash dishes, but if you hire 14- and 15-year-olds, federal law limits their hours and some tasks. The interview is short and has to find out two things: whether the candidate will show up for every shift, especially Friday and Saturday nights, and whether they can keep up under pressure without cutting corners on sanitizing, chemicals and safety. Everything else, including your machine and your racks, you teach on the first shift.

What to settle before the interview

Dishwashing has no license, so the checks before the interview are about hours and age.

• The schedule, in hours. BLS notes that food service shifts “often include early mornings, late evenings, weekends, and holidays.” Put your actual shifts in the job ad, including when close usually ends. “Evenings” means 10pm to one person and 1am to another.
• Age, if you hire teenagers. Federal rules allow 14- and 15-year-olds to do kitchen work, and 29 CFR 570.34(i) lists dishwashers among the permitted machines. Cleaning kitchen equipment is also allowed, but only when the equipment, surfaces, containers and liquids do not exceed 100°F. Hours are limited under 29 CFR 570.35: no more than 3 hours on a school day and 18 in a school week, 8 on a non-school day and 40 in a non-school week, and only between 7 a.m. and 7 p.m. (9 p.m. from June 1 through Labor Day). A 15-year-old cannot close your dish pit at 10pm on a school night, however good the interview. States can be stricter; see child labor laws by state and interview questions for teenagers.
• Transportation. If close ends after the buses stop, ask in the pre-screen how the candidate gets home. Do not assume.

If the role is not written down yet, start from the dishwasher job description. Many kitchens also hire dishwashers on the spot; if you do, see on-the-spot hiring and walk-in interviews for how to keep it fair and quick.

Nine dishwasher interview questions

A dishwasher interview should take fifteen to twenty minutes. Ask the same questions of every candidate and write the answers down; it is easy to hire the most talkative person in a role where talking is not the job. If you can, follow up with a short paid working interview during a busy service.

“When did you last miss a shift or show up late, and how did your manager find out?”

Attendance is the whole job. A dish pit that is empty at 6pm on a Saturday stops the line within the hour. Ask it exactly this way, not “are you reliable?” The strong answer is specific: a date, a reason, a phone call before the shift. The weak answer is “I never miss” with nothing behind it, or a story in which the manager found out when they did not appear. Explain your no-call no-show policy now, not on day one.

“It's Friday at 7. Racks are stacked, the line needs sauté pans, and the servers are out of forks. What do you do first?”

There is no single right order, which is why you ask. Strong candidates think about what stops service first: pans for the line and silverware for the floor before the stockpots, and telling the line or the manager what is coming and how long it will take. Weak candidates start at the top of the pile, or say they would “just go faster.”

“How do you know the dish machine is actually sanitizing?”

Candidates who have worked a machine will mention checking the temperature gauge or using test strips for the sanitizer, depending on the machine, and telling a manager when a reading is off. Candidates new to kitchens will not know, and that is fine; what matters is how they answer. “I don't know, I'd ask” is a good answer. “It's automatic, it just works” is not.

“You're using a cleaning chemical you don't recognize. What do you do?”

The strong answer: read the label, ask, never mix chemicals, and wear the gloves or eye protection the label calls for. Some candidates will mention the safety data sheet binder. The weak answer is to use whatever is under the sink the way they used something similar somewhere else.

“There's broken glass in the sink water. Walk me through it.”

Every dishwasher faces it eventually. Strong candidates stop, drain the sink rather than reaching in, remove the glass with tongs or a scoop, tell the line if glass could be near food, and dispose of it separately. Anyone who would reach in and feel around is a cut waiting to happen.

“Tell me about the busiest kitchen you've worked in. What was a bad night like?”

Listen for detail: covers per night, the machine, how many people in the pit. A candidate who has been through a slammed service describes it with some calm, even pride. A first-job candidate cannot answer this, so ask about the busiest they have been anywhere: a sports team, a family business, a school event.

“A cook yells at you because pans aren't coming back fast enough. What do you do?”

Kitchens get loud. The strong answer is to tell the cook what is coming and how long, keep working, and raise it with the manager later if it becomes a habit. Weak answers either escalate on the spot or say they would walk out. This question also tells you something about your own kitchen: if candidates flinch, ask yourself how often it happens.

“What shifts can't you work?”

Ask what they cannot do, not whether they are available. Candidates who want the job say yes to everything. A second job, school, a last bus or child care pickup is not disqualifying, but you need it before the schedule is written.

“Would you want to learn prep or the line?”

Many cooks started in the dish pit. A candidate who wants to move up is a candidate with a reason to stay, and cross-training covers you when a prep cook calls out. Say what the path looks like in your kitchen. Candidates who only want to wash dishes are also fine; some of the most reliable dishwashers stay for years.

Red flags, and what is not a red flag

• Red flag: vague answers about attendance after two direct questions.
• Red flag: casual about chemicals, glass or hot water.
• Red flag: walked out mid-shift from a past job and presents it as normal.
• Not a red flag: no kitchen experience. The machine is taught in an hour; attendance and attitude are not.
• Not a red flag: short stints at several restaurants. Closures and cut hours are common. Ask why each ended.
• Not a red flag: limited English, if your kitchen can train and work with it. Judge the job, not the conversation.

Questions not to ask

Short, informal interviews are where risky questions slip in. Avoid asking about national origin or where someone is “really from,” age beyond confirming the legal minimum for the job, children, pregnancy, religion, health or disability. Work authorization is verified on the Form I-9 after hire, not by questioning in the interview. See illegal interview questions for the full list.

How to score it

Score each answer from 1 to 4 as the candidate gives it. Weight attendance and the Friday-night priority question most heavily, and treat a careless answer on glass or chemicals as disqualifying. When two candidates are close, the one who scored higher on attendance is usually the better hire. The interview scorecard template takes two minutes to fill in.

Pay, and what it means for your offer

O*NET, republishing BLS data, reports a 2025 median of $16.73 an hour ($34,810 a year) for dishwashers, across about 477,700 jobs (2024), with about 76,800 openings projected each year and little or no change in employment. A neighboring BLS group, food and beverage serving and related workers (it does not include dishwashers), had a May 2025 median of $15.24 an hour. Where the group works matters:

These are group figures, not dishwasher-specific, but they show the pattern: hospital, school and hotel kitchens tend to pay food service workers more than restaurants, and often with daytime hours. A restaurant hiring a dishwasher competes with those kitchens and with every warehouse and retail job nearby. Your offer has to cover the basics well: a posted schedule, a shift meal, how tips are shared with the back of house if they are, and a path to prep. With about 76,800 openings a year for an occupation of about 477,700, turnover is constant; see restaurant turnover rate.
