Walk me through your recent prep or kitchen experience and your key responsibilities.

Sample Answer: I’ve spent the last year on a high-volume prep team handling vegetables, sauces, and cold station mise en place. I set pars, labeled and dated items, rotated stock, and supported the line during peak times by refilling backups and communicating low counts.

What a Strong Answer Includes

• Clear summary of stations, volume, and typical mise en place tasks
• Specifics on labeling, dating, and rotation habits
• Examples of reliability, pace, and teamwork during service

Describe how you prevent cross-contamination during prep.

Sample Answer: I use color-coded boards and separate tools for raw and ready-to-eat items, sanitize surfaces between tasks, and change gloves after handling raw proteins. I also keep raw proteins stored below ready-to-eat foods and verify temps with a clean, sanitized thermometer.

What a Strong Answer Includes

• Concrete steps: separate boards/tools, glove changes, sanitize between tasks
• Storage hierarchy and thermometer hygiene
• Awareness of cross-contact for allergens, not just raw vs. cooked

Explain how you organize the cooler/walk-in and apply FIFO.

Sample Answer: I set raw poultry on the lowest shelves, then other raw meats, with ready-to-eat foods and produce above, and always label/date items. I rotate stock daily, pull older product forward, and log any low or expiring items so ordering or prep can adjust.

What a Strong Answer Includes

• Correct storage order and dating/labeling
• Daily rotation and FIFO with practical examples
• Proactive communication about low or expiring items

What is your approach to allergen-safe or special-diet prep?

Sample Answer: I prep in a cleaned, designated area with sanitized tools and, when possible, dedicated equipment for allergen-free items. I verify ingredients, label clearly, and keep finished items covered and separate to avoid cross-contact.

What a Strong Answer Includes

• Separate workspace/tools and strict sanitation before starting
• Ingredient verification, clear labeling, and covered storage
• Understanding of cross-contact risks and ticket accuracy

Which knife cuts are you most confident with, and how do you keep your knives in top condition?

Sample Answer: I’m comfortable with small/medium dice, julienne, chiffonade, and brunoise, and I keep sizes consistent for even cooking. I hone before shifts, sharpen regularly, use a non-slip mat, and work with a stable pinch grip and claw technique for safety.

What a Strong Answer Includes

• Named cuts with attention to uniformity and size
• Daily honing, periodic sharpening, and safe setup
• Efficient, safe technique (pinch grip, claw, stable board)

How do you prioritize a prep list when time is tight?

Sample Answer: I triage by service impact and lead times, tackling long-cook or high-volume items first and batching similar tasks to reduce setup changes. I confirm priorities with the chef and give quick updates if we need to swap tasks.

What a Strong Answer Includes

• Logical prioritization tied to service impact and lead times
• Batching and station organization to reduce changeovers
• Active communication when priorities shift

What do you do to ensure the line never runs out of prepped items during a rush?

Sample Answer: I do a pre-shift check against pars, stage labeled backups, and keep a running tally during service. If an item dips, I communicate immediately and start a quick re-prep or swap in an approved backup.

What a Strong Answer Includes

• Pre-shift inventory against pars and staging backups
• Real-time monitoring and clear alerts to the line
• Rapid re-prep plan or pre-approved substitutions

How do you communicate with the kitchen team during a busy service?

Sample Answer: I keep callouts short and specific, confirm when requests are received, and provide quick updates on low counts. I listen for direction from the lead and escalate early if something risks slowing the line.

What a Strong Answer Includes

• Concise, clear callouts and confirmations
• Active listening and alignment with lead/chef direction
• Proactive updates about shortages or delays

Tell me about a time you made a prep mistake—how did you fix it and prevent it from happening again?

Sample Answer: I mislabeled a batch once, owned it immediately, discarded the questionable item, and re-prepped the batch to spec. Afterward, I added a double-check step before labeling and asked a teammate to verify until it became habit.

What a Strong Answer Includes

• Ownership and fast, food-safe corrective action
• Clear communication to protect service and guests
• Specific process change that prevents repeat errors

What strategies do you use to minimize waste during prep?

Sample Answer: I set accurate yields, use trim for stocks or specials when appropriate, and adjust batch sizes to match recent sales and pars. I track waste patterns and share notes so ordering and prep can be tuned.

What a Strong Answer Includes

• Yield awareness and smart repurposing of usable trim
• FIFO, portioning consistency, and right-sized batches
• Communication of waste trends to improve ordering

For employers: validate skills with a short practical and observe safety, speed, and organization.

• Run a quick knife test (e.g., dice an onion, slice tomatoes); watch consistency, finger safety, and board setup.
• After the demo, look for professional habits: labeling, dating, wrapping, and proper storage placement.
• Probe sanitation literacy with brief follow-ups on storage hierarchy, glove changes, and allergen handling.

For candidates: show reliability, sanitation awareness, and eagerness to learn.

• Study the menu, arrive early, and bring a positive, coachable attitude; be honest about gaps.
• Refresh basic knife cuts and safe workstation setup; ask clarifying questions to avoid waste.
• Be ready to discuss availability, pace under pressure, and how you keep stations clean and organized.
