Sample Answer
Once while cleaning a large office, I encountered a major water leak. Water was pouring from a broken pipe, and the office was beginning to flood. I immediately shut off the main water supply and contacted the building’s maintenance team. I also quickly moved electronics and other sensitive items to higher ground to prevent damage. The situation was stressful, but I managed to minimize the damage and clean up the water before it could cause major issues.

Sample Answer
Safety is always my top priority when handling cleaning chemicals. I always ensure to wear the appropriate protective equipment like gloves and goggles. I read and follow the manufacturer’s instructions carefully and I never mix chemicals unless it’s specified that it’s safe to do so. I also make sure to properly store and dispose of chemicals after use. Lastly, I always ensure that the area is well-ventilated to minimize the risk of inhaling harmful fumes.

Sample Answer
When I have a large area to clean within a certain time limit, I always start by assessing the whole area first. I then prioritize tasks based on the urgency and visibility of the area. For instance, I would prioritize areas with high foot traffic or where customers frequently visit. After that, I move on to less visible areas or places that are not in immediate use. I also try to be efficient by grouping tasks that can be done together, like sweeping and mopping. This way, I can ensure that all areas are cleaned within the given time frame without compromising the quality of my work.

Sample Answer
I believe in staying organized and keeping a strict inventory of all my cleaning supplies. I use a digital inventory system to keep track of what I have and what I need. I check my inventory at the end of each week, and based on the level of supplies, I determine if I need to order anything for the coming week. If a supply is running low and I know it’s heavily used, I make sure to order it in advance so I never run out. I also keep a small reserve of essential items, just in case.

Sample Answer
When dealing with potentially hazardous waste or materials, my first step is to always ensure I’m wearing the appropriate protective equipment, such as gloves and a mask. I would then carefully contain the waste in accordance with safety guidelines, ensuring not to mix different types of waste. Once contained, I would dispose of the waste in designated areas or containers. I also make sure to wash my hands thoroughly after handling such materials. In my previous role, I received training on handling hazardous materials, and I always follow these protocols to the letter to ensure safety.

Sample Answer
In my opinion, one of the most challenging aspects of a janitor’s work is responding to and managing unexpected messes or spills. These can occur at any time and require immediate attention to prevent accidents or further damage. To handle this, I always ensure I have the necessary cleaning supplies on hand and prioritize these tasks to ensure safety. I also try to keep calm and composed during these situations because I believe that efficiency comes with a clear mind.

Sample Answer
At my previous job, our management decided to implement a new cleaning protocol due to the pandemic. Initially, I was overwhelmed because it meant learning new procedures and using new chemicals I wasn’t familiar with. However, I understood that it was necessary for everyone’s safety. I took the initiative to study the new protocol, ask questions when in doubt, and even did some practice runs to get comfortable. Within a week, I was able to adapt to the new procedures and even trained my colleagues. This experience taught me the importance of adaptability and continuous learning in maintaining a safe and clean environment.

Sample Answer
From my previous experience, I’ve learned that communication is key in such situations. I usually approach the individuals in the area and inform them about the cleaning schedule. I try to negotiate a time that suits them and does not interfere with their tasks, or I suggest alternative spaces they can use while I clean. My goal is to ensure that I do my job efficiently without causing any inconvenience to others.

Sample Answer
In my previous job, there was a time when I encountered a stubborn stain on the office carpet that wouldn’t come out with our standard cleaning solutions. I first tried to identify the cause of the stain, and then researched about different cleaning methods that could work. I found a different cleaning solution that was safe to use on the carpet and effective for the type of stain. I tested it on a small, inconspicuous area to ensure it wouldn’t damage the carpet, and then used it to successfully remove the stain. However, I also know that it’s important to ask for advice when needed, so if I were to encounter a situation that I couldn’t handle, I wouldn’t hesitate to seek help.

Sample Answer
If I noticed a co-worker not following safety protocols, I would gently remind them of the importance of these rules for our well-being. If the behavior persisted, I would report it to my supervisor to ensure everyone’s safety.
