10 Crucial Interview Questions for Custodian/Janitor in Education & School Districts with AI Recruiter Automation

Finding reliable custodial staff for school districts has become one of the most challenging hiring tasks in education today. According to the U.S. Bureau of Labor Statistics, the custodial services sector is experiencing a 7% turnover rate annually, with educational institutions hit particularly hard by staffing shortages. A recent SHRM study revealed that the average cost per hire for facilities positions now exceeds $4,700, with time-to-fill averaging 42 days—time schools simply don’t have when cleanliness and safety are non-negotiable.

The challenge isn’t just finding candidates; it’s engaging them quickly before they accept offers elsewhere. Research shows that 60% of candidates drop off during lengthy application processes, and custodial positions see even higher abandonment rates when applicants face cumbersome forms and delayed responses. Meanwhile, school districts are competing with private sector facilities management companies that often move faster and offer more flexibility.

That’s where CloudApper AI Recruiter transforms the game.

Why These Questions Matter for Custodian/Janitor Roles in Education

The custodian role in schools has evolved dramatically beyond basic cleaning. Today’s school custodians are safety officers, minor maintenance technicians, and the first line of defense against health hazards. Post-pandemic, custodians must understand disinfection protocols, chemical safety regulations, and OSHA compliance. They work with specialized equipment, manage supply inventories, and often coordinate with multiple departments.

Old interview questions like “Can you mop floors?” no longer cut it. Modern custodian interview questions for education must assess technical knowledge, safety awareness, problem-solving under pressure, and the ability to work in environments with children. Schools need custodians who understand the unique demands of educational facilities—from handling gym equipment to managing spills during lunch rushes to maintaining bathrooms between class changes. The best custodian interview questions dig into real scenarios candidates will face daily while revealing their professionalism, reliability, and fit with school culture.

Top 10 Essential Custodian/Janitor Interview Questions to Ask (Plus How AI Recruiter Can Automate The Entire Hiring Process)

1. Describe your experience cleaning and maintaining facilities similar to schools. What types of buildings have you worked in?

Why ask this? This establishes relevant experience and helps you understand whether the candidate grasps the unique challenges of educational environments versus offices, hospitals, or retail spaces.

Sample Strong Answer: “I’ve worked in educational facilities for the past five years, primarily in middle schools and high schools. Before that, I spent three years maintaining a community center that hosted youth programs. School environments require extra attention to high-traffic areas like cafeterias and hallways during transitions, plus awareness of children’s safety. I’m experienced with maintaining gyms, locker rooms, classrooms, and administrative offices. I understand that schools have specific cleaning windows—often before students arrive or after they leave—and I’m comfortable working those schedules.”

2. What cleaning chemicals and disinfectants are you familiar with, and how do you ensure proper safety when using them?

Why ask this? Chemical safety is critical in schools where children are present. This question assesses technical knowledge and safety consciousness.

Sample Strong Answer: “I’m trained in using EPA-registered disinfectants, including quaternary ammonium compounds for general disinfection and bleach solutions for specific applications. I always read Safety Data Sheets before using any product and follow manufacturer dilution ratios exactly. In school settings, I’m particularly careful to ventilate areas properly, post wet floor signs, and never mix chemicals. I also ensure cleaning products are stored in locked areas away from students and understand requirements around green cleaning products that many districts now mandate.”

3. How would you handle an emergency situation like a sewage backup or hazardous spill during school hours?

Why ask this? Schools face unexpected situations that require quick thinking and proper protocol adherence.

Sample Strong Answer: “My first priority would be to secure the area immediately—setting up barriers and signage to keep students and staff away. I’d notify my supervisor and the school office right away so they can make building-wide announcements if needed. For sewage backups, I’d shut off water if possible and call for specialized cleanup since it’s a biohazard. For chemical spills, I’d reference the SDS, use appropriate PPE, and contain it with absorbent materials. I’d never attempt something beyond my training—knowing when to call in specialists is part of being professional. Throughout, I’d document everything and complete incident reports per district policy.”

4. What experience do you have with floor care equipment like buffers, strippers, and auto-scrubbers?

Why ask this? Schools have diverse flooring that requires specialized equipment knowledge.

Sample Strong Answer: “I’m experienced operating electric floor buffers and burnishers up to 20-inch models, and I’ve used automatic scrubbers for large spaces like gymnasiums and hallways. I understand the differences between stripping, scrubbing, and maintaining various floor types—VCT, sealed concrete, and hardwood gym floors each require different approaches. I perform routine maintenance on equipment, including changing pads, emptying recovery tanks, and basic troubleshooting. I’ve also been trained on proper cord management to prevent trip hazards and ensure equipment longevity.”

5. Schools operate on tight schedules with specific cleaning windows. How do you prioritize tasks when you have limited time?

Why ask this? Time management and prioritization are essential in the school environment.

Sample Strong Answer: “I work from a priority checklist that puts health and safety first—bathrooms, cafeterias, and high-touch surfaces like door handles and handrails get cleaned multiple times daily. I know that certain tasks must happen during specific windows; for example, gym floors can only be buffed after sports activities end. I tackle high-visibility areas before school starts so students and staff walk into clean spaces. For larger projects like stripping floors or deep-cleaning, I coordinate with administration to schedule during breaks or weekends. I’m also flexible—if there’s a lunchroom spill or bathroom issue, I drop what I’m doing because student safety can’t wait.”

6. How do you approach working around children and maintaining appropriate boundaries?

Why ask this? Custodians interact with students daily and must maintain professional boundaries while being approachable.

Sample Strong Answer: “I treat interactions with students professionally and kindly but maintain clear boundaries. If students try to engage in extended conversations while I’m working, I’m polite but redirect them to class or their activities. I never discipline students—that’s not my role—but I will notify teachers or administrators if I observe concerning behavior. I’m also careful about situations where I might be alone with a student; I keep doors open and position myself visibly. Many kids don’t notice custodians, which is fine, but when they do acknowledge me or say thanks, I appreciate it and respond respectfully. I understand I’m part of the school community and take that responsibility seriously.”

7. Tell me about a time you identified a maintenance or safety issue before it became a major problem.

Why ask this? Proactive problem-solving prevents costly repairs and potential safety incidents.

Sample Strong Answer: “At my last school, I noticed water staining on ceiling tiles in one hallway. Instead of just replacing the tiles, I reported it to maintenance because I suspected a roof leak. It turned out there was a small leak that would have caused major damage if left unaddressed. Another time, I noticed a playground gate latch was becoming loose—kids were still using it safely, but I could see it would fail soon. I tagged it and reported it immediately so it could be repaired before it became a safety hazard. I believe part of my job is being the eyes and ears of the building, catching small issues before they become expensive emergencies.”

8. What’s your approach to maintaining restrooms throughout the school day?

Why ask this? Restroom maintenance is one of the most critical and challenging aspects of school custodial work.

Sample Strong Answer: “Restrooms require constant attention in schools. I check them on a rotation throughout the day—at minimum between morning arrival and first period, mid-morning, after lunch, and before dismissal. Each check involves restocking supplies, spot cleaning sinks and toilets, mopping up water, and removing any graffiti immediately. I also look for maintenance issues like running toilets or broken dispensers. I understand that clean restrooms directly impact student comfort and health, so I don’t skip checks even when other tasks pile up. I also keep restroom cleaning carts stocked and organized so I can respond quickly to urgent situations.”

9. How do you stay updated on cleaning best practices, safety regulations, and new equipment?

Why ask this? This reveals commitment to professional development and adaptability.

Sample Strong Answer: “I take training seriously because methods and regulations change. I’ve completed OSHA 10-hour safety training and maintain bloodborne pathogen certification. When my district offers professional development sessions on new equipment or green cleaning products, I attend. I also learn from manufacturer representatives when new equipment is introduced—they often provide better insights than just reading manuals. I’m part of a local custodians’ association where we share challenges and solutions. I believe staying current makes me more valuable to my employer and helps me work more efficiently and safely.”

10. Why do you want to work specifically in a school environment, and what does excellent custodial work look like to you?

Why ask this? This assesses motivation, understanding of the role’s impact, and alignment with school values.

Sample Strong Answer: “I want to work in schools because education matters, and I take pride in knowing my work directly supports student learning. Kids can’t focus in dirty or unsafe environments, so when I maintain clean classrooms, functioning bathrooms, and safe hallways, I’m contributing to their success. Excellent custodial work means students and teachers don’t have to think about cleanliness—it’s just there. It means responding quickly when issues arise, taking initiative on projects, and working as part of the school team. It also means representing the district professionally because I’m often the first person visitors see. I find purpose in work that serves the community, especially when it involves helping kids have the best possible environment to learn and grow.”
