Janitorial interviews are practical and focus on reliability, attention to detail, and safety knowledge. Hiring managers need someone they can trust to maintain their building after hours with minimal supervision. Expect questions about your cleaning routine, chemical handling, and how you manage your time across a large facility. Show that you take the work seriously and treat it as a skilled profession, not just a job.
Use the sections below as a general guide for janitors & cleaner interviews. When you create a free account, Bespree generates personalized interview prep structured around your actual resume and target job.
What interviewers look for
- Reliable attendance for every scheduled shift — janitorial work depends on consistency
- Trustworthiness and integrity when working alone in secure environments
- Knowledge of cleaning procedures, chemicals, and equipment
- Ability to identify and report maintenance issues proactively
- Physical fitness for sustained cleaning work across large facilities
Common mistakes
- Not describing a structured cleaning routine — 'I just clean everything' is too vague
- Underestimating chemical safety — hiring managers take this seriously
- Not asking about facility size, shift hours, or equipment
- Saying you prefer daytime work when the role is evening or overnight
- Not mentioning any floor care or specialized cleaning skills
Strengths to highlight
- Experience maintaining commercial, office, or institutional facilities
- Knowledge of cleaning equipment: floor buffers, extractors, and pressure washers
- Understanding of proper chemical handling and MSDS/SDS compliance
- Ability to work independently during off-hours or overnight shifts
- Attention to detail in maintaining building appearance and sanitation
“Tell me about yourself”
A strong answer should briefly explain your background, experience, and what you want next.
I have been working in janitorial services for three years, most recently in a four-story office building where I am responsible for cleaning about 30,000 square feet per shift. I handle everything from nightly restroom sanitation and trash removal to weekly floor care and window cleaning. I work independently during evening hours and I take pride in keeping the building looking professional. I am detail-oriented, I follow proper chemical safety procedures, and I report maintenance issues promptly. I am looking for a facility that values its cleaning staff and maintains its equipment properly.
Key points to include
- Mention the size and type of facility you have cleaned
- Show that you work independently and take ownership of your building
- Highlight chemical safety knowledge — it matters to hiring managers
- Express standards — shows you take the work seriously
Common janitors & cleaner interview questions
5 questions with sample answer frameworks.
Describe your nightly cleaning routine for an office building.
Why this may come up: This tests whether you have a systematic approach and understand the full scope of janitorial duties.
Sample answer framework
I start with the restrooms because they need the most attention and the disinfectant needs contact time. While the restroom chemicals sit, I empty trash and recycling throughout the floors. Then I come back to finish the restrooms: scrub toilets and sinks, mop floors, restock supplies. After that, I wipe down common area surfaces — break room, conference tables, door handles — and vacuum the carpeted areas. I finish with hard floor mopping in hallways and the lobby. I do a final walkthrough, check that all lights are off where they should be, and lock up.
How do you handle a biohazard situation like bodily fluids in a restroom?
Why this may come up: Biohazard cleanup requires specific procedures. This tests your safety knowledge and composure.
Sample answer framework
I put on full PPE: gloves, face shield, and an apron if available. I block off the area so nobody walks through it. I use a bloodborne pathogen cleanup kit if available, or hospital-grade disinfectant and absorbent materials. I clean the area following the outward-in method to avoid spreading contamination, then apply disinfectant and let it sit for the required contact time. I dispose of all contaminated materials in a designated biohazard bag. After cleanup, I wash my hands thoroughly and document the incident. I never handle biohazards with regular cleaning supplies.
What do you do when you find something broken or a maintenance issue while cleaning?
Why this may come up: Janitors are often the first to spot building issues. This tests your communication and responsibility.
Sample answer framework
I document it immediately — what it is, where it is, and whether it is a safety hazard. If it is urgent — a water leak, broken glass, or an electrical issue — I report it to the building manager or after-hours emergency contact right away and secure the area. If it is non-urgent — a loose toilet handle, a flickering light — I log it in the maintenance request system so it gets addressed. I do not try to fix things outside my scope, but I make sure nothing gets overlooked because I assumed someone else would report it.
Are you comfortable working alone during evening or overnight shifts?
Why this may come up: Most janitorial work happens during off-hours. This tests your reliability and independence.
Sample answer framework
Yes, I prefer working during off-hours because I can be more thorough without working around building occupants. I am self-motivated and I follow my cleaning schedule consistently whether anyone is watching or not. I carry a radio or phone in case I need to contact the building management or security. Working alone requires discipline — you have to hold yourself to the same standard every night, because the quality of your work only shows up when people arrive in the morning.
How do you handle floor care — do you have experience with stripping and waxing?
Why this may come up: Floor care is a specialized skill that separates experienced janitors from basic cleaning staff.
Sample answer framework
I have experience with VCT floor care including stripping, waxing, and buffing. For a strip-and-wax job, I start by dry-mopping to remove debris, then apply stripper solution with a mop and let it sit before using a floor machine with a stripping pad. I rinse thoroughly to remove all residue — this is the step most people rush and it ruins the wax job later. Then I apply three to four thin coats of floor finish, letting each one dry before the next. I finish with a high-speed burnish for shine. Proper floor care takes patience, but it makes a building look professional.
STAR Stories
Behavioral questions ask you to describe real situations. The STAR format (Situation, Task, Action, Result) gives your answer a clear structure that interviewers can follow.
For janitors & cleaner roles, prepare stories that highlight your ability to handle difficult situations, collaborate effectively, and deliver results under pressure. When you sign in, Bespree actually builds personalized STAR stories drawn directly from your resume bullets — ready to practice with.
Questions to ask the interviewer
Good questions show that you care about fit, expectations, and how the company operates.
- What is the square footage and type of the facility I would be cleaning?
- What shift hours are available, and is there flexibility?
- What cleaning equipment and chemicals does the company provide?
- Is there a supervisor on site during my shift, or do I work independently?
- What does the path to promotion look like — lead janitor, facilities coordinator?
Tips by experience level
Entry-level / apprentice
If you are new to janitorial work, emphasize your reliability, physical fitness, and willingness to learn. Mention any related experience: cleaning at home, volunteer work, or retail stocking. Show that you understand the core of the job is being thorough, showing up consistently, and maintaining a building to a professional standard. Entry-level janitorial hiring prioritizes work ethic and reliability above all else.
Experienced / journeyman+
If you have janitorial experience, lead with the type and size of facilities you have maintained. Mention specialized skills like floor care, carpet extraction, or window cleaning. Note any supervisory experience or equipment certifications. Experienced janitors who can demonstrate consistent quality and independence are strong candidates for lead, shift supervisor, or facilities coordinator roles.
