The questions

1
Behavioral
How do you plan your route so everything gets done in a shift?
Show sample answer ▾

I start with the areas that need dry time, like floors being stripped or extracted, and work toward the exit. I do trash and restrooms early so they're ready for the morning, and dust high-to-low so debris falls before I vacuum. I check the checklist at the end.

2
Technical
What would you do if you found a spill of an unlabeled chemical?
Show sample answer ▾

I wouldn't touch it. I'd keep people away, put on gloves and eye protection, ventilate if I can and report it to my supervisor so it can be identified and handled. I'd then check the safety data sheet to know how to clean it up.

3
Technical
How do you avoid cross-contamination between restrooms and other areas?
Show sample answer ▾

I use color-coded cloths and mops, one color per area, clean restrooms with their own supplies and change gloves between areas. I never reuse a restroom cloth anywhere else.

4
Behavioral
Tell me about a time you noticed a problem that wasn't your job to fix.
Show sample answer ▾

I saw a ceiling stain growing near a stairwell. I took a photo, reported it to the facilities manager that night and taped off the floor. They found a roof leak the next day before it damaged more of the building.

5
Culture
How do you handle working alone in a large building at night?
Show sample answer ▾

I follow the check-in and lock-up procedures, carry a phone or radio, keep doors secured behind me and stay aware of who is in the building. I report anything unusual rather than investigate it alone.

6
Behavioral
What do you do when you are asked to do extra work that doesn't fit the shift?
Show sample answer ▾

I tell the supervisor what would be left undone and let them choose the priority. I'd rather agree on the plan than rush and do poor work.

How to prepare — the STAR rubric

Every strong behavioral answer follows the same four-part structure: Situation(the context — 2 sentences), Task (what success looked like — 1 sentence),Action (what you actually did, 3-5 specific steps), and Result(the measurable outcome). Most candidates over-invest in Situation and under-invest in Result. The Result is where the interviewer scores you.
