5. What Significant Challenges Did You Face In Your Previous Position? How Were They Handled By You?

The janitorial position requires very little formal training. This is a result of the variety of roles played. The majority of abilities are acquired by a janitor on the job. This caused me issues, particularly throughout the winter. It was challenging to deal with mud in the spring and rock salts in the winter. But until I achieved the necessary degree of cleanliness, I experimented with many chemicals and put in additional work.

6. Describe Your Janitorial Workday In Detail.

I start working early in the morning or perhaps late at night on a regular day. I gather the tools and resources I’ll need for the work. I submit materials and assign various duties to my team members at the work site. I emptied the building’s garbage and recycling containers and placed the contents in dumpsters. My crew and I clean the tables and stack the chairs before we begin cleaning or washing the floors. After that, I clean the restrooms and, if necessary, buy new paper towels, hand soap, and toilet paper. When I have completed all the chores, I check the priority list to ensure I have completed each one.

High turnover will be the biggest obstacle in this position, in my opinion. The majority of individuals do not see cleaning work as a career. The job’s requirements account for this. It’s simple to get exhausted fast. However, a company’s culture may help keep its janitors by showcasing excellent leadership, paying them well, and providing on-the-job training.

13. If You Find A Major Problem During Cleaning, What Will You Do?

I will adhere to the company’s reporting guidelines. The problem will be brought to my supervisor’s attention so that the proper authorities may be contacted. But this varies from problem to problem.

When I started this line of work, I saw that people showed little regard for janitors. The way they would speak and interact with us. Other workers would constantly gripe about incomplete jobs that were outside of our purview but that they expected us to do. I was so demoralized by this that I stopped taking pride in my profession as a janitor. My ego and sense of self-worth suffered, and before I realized it, I was sad. I was shocked to be selected as the best employee of the year at the end-of-year staff meeting. I was handed the trophy and a sizable amount of money as a token of appreciation. Even though other employees looked down on me, I was glad to know that the management appreciated my service. I learned from this to always put my best self forward, no matter what people think or say.

16. Why Do You Feel You Are Qualified For This Role?

In addition, I have strong organizational, time-management, and communication abilities that enable me to fulfill my tasks effectively. Task prioritization and on-time completion are skills I possess. I am sure that my qualifications, attributes, and experience will help me succeed in this opportunity.

17. How Do You Prioritize And Plan Your Work As A Cleaner?

I like beginning my job in quiet, open areas with few distractions. It is simpler to generate momentum when I have minor victories early in the day. I continue till I get to the occupied spots that need further work. I next go on to clean the public areas, which must be done often to stay in top shape.

18. Describe Your Best Success To Us

My coworkers selected me as the best janitor of the year twice in a row in my prior position as a janitor. This gave me reassurance that my contributions were valued and appreciated. Working hard may pay off and, in my opinion, lead to more opportunities than one would anticipate. Because of this, I approach my job with a self-driven mindset, even when I’m in a hectic setting. I’m working harder now to keep this job. Should you decide to recruit me for this position, I will make the most of my strong traits, expertise, and experience to ensure I will be the company’s best employee of the year.

19. What Would You Do If A Harmful Chemical Spill Occurred At Work?

If chemicals spill on a surface, I am equipped to clean it up fast. I would clean the impacted area with the appropriate cleaning solution. I’ll make sure to adhere to the business’ typical emergency protocol. While sanitizing the spilled area, I shall also adhere to my state’s occupational health and safety regulations.

20. Do You Have Any Experience Handling Customer Complaints?

Absolutely, I did. The consumer voiced complaints about the quality of the service during a call to customer support. I was enraged by this. The customer shouldn’t condemn the business solely on the conduct of one person since we are dedicated to excellence. They were sent to another customer support team member, who was delighted to assist them. In the end, the client was content. I didn’t anticipate this since I assumed my job would be over when he walked into the office.

21. What Would You Do If You Ran Out Of Cleaning Supplies But Still Had Work To Do?

I regularly check my cleaning materials and products so I can refill them as necessary to prevent difficulties. For reasons of accountability and refilling, I maintain a log of my cleaning supplies. However, I would let my boss know if they suddenly ran out. On the other hand, if the cleaning supplies must be purchased ahead, I would postpone the cleaning time but do other activities, such as sweeping and vacuuming.

22. How Will You Perform Your Duties If Others Are Around?

I’ll kindly let everyone know if I need to clean certain equipment or a specific location. However, if I have to mop the floor, I’ll start by setting up foldable warning signs. I will also be accommodating if any individuals wish to utilize the space. I’ll let them use it and ask them to let me know when they’re done so I can start cleaning it again. I’ll turn to other things while I wait to hear from you again.

23. How Should Public Spaces Be Cleaned When People Are Present?

The frequent traffic in the area tends to sometimes ruin the cleaning effort. There should be signs indicating that cleaning is done and that the floor is moist and slick. People will steer clear of the region as a result. Public spaces may sometimes get exceedingly untidy, mainly when there is an event, an exhibition, or a holiday. Despite having separate containers available, people continue to discard a lot of trash. However, I don’t mind since I like being of service to others. I never seem to become annoyed by this.

24. Briefly Describe Some Essential Cleaning Supplies And Equipment You Have Previously Used.

I have utilized various cleaning supplies in my prior position as a janitor, including bleach, air fresheners, sanitizers, toilet cleansers, dishwashing liquids, and home cleaners. I also understand how to use the proper materials appropriately without endangering my cleaning area. Additionally, I am proficient in using various equipment, including floor scrubbers, floor polishers, carpet cleaners, brooms, dustpans, buckets, vacuum cleaners, rubber gloves, Squeegees, toilet brushes, and holders.

25. Could You Describe How You Use Cleaning Products?

I use a range of cleaning products, including conventional and natural kinds.

Some of these remedies are:

  • All-purpose cleaner: I use this solution to remove dirt, stains, and oil from many surfaces.
  • Glass cleaner: I use glass cleaner to clean surfaces made of glass, such as windows and tables. It removes dirt without leaving behind stains or streaks.
  • Tile cleaner with bleach: I use this remedy to remove rust, soap scum, mildew, and mold from surfaces.
  • White vinegar: I use this mixture to remove grime and dissolve oil. Additionally, I disinfect using it.


You should take some time to prepare for the interview and rehearse your responses to these questions in advance, especially if you get anxious in interviews. This is an excellent strategy to avoid having a speech impediment during the interview.

The easiest method to achieve this is to find a buddy who will play the role of the interviewer for you in a role-playing exercise. The objective is to be well-rehearsed in your replies before you enter the interview room, but in the absence of this, talking aloud to your mirror is equally beneficial.

Eat a satisfying and nutritious meal the morning before the interview; refrain from drinking too much coffee if it makes you jittery. Make sure you look well for your interview by dressing neatly and professionally. As the employer’s custodian, you must keep the workplace tidy. When going to your interview, you should allow extra time in case of traffic or other delays; if at all feasible, try to arrive a few minutes early.
