Additionally, a janitor must know different safety guidelines while working with chemical cleaners.

4. What Major Challenges Did You Face During Your Last Role? How Did You Manage Them?

There is very minimal training in the janitorial role. This is due to the variation of roles involved.  A janitor learns most of the skills while doing the job. This gave me problems, especially during winter periods.  Dealing with rock salts in the winter and mud in the spring was a big challenge. However, I did a lot of chemical experimentation and added more effort to the job till I got the level of cleaning that was required.

On a typical day, I begin my work early in the morning or sometimes in the evening. I collect the supplies and the equipment that I need to do the job. At the job site, I upload materials and delegate some tasks to my team members. I empty trash and recycle bins in the building including throwing them in dumpsters. With my team, we wipe tables and stack furniture so that we can start vacuuming or mopping floors. I then sanitize bathrooms and replace paper towels, hand soap, and toilet paper as needed. Once, I am done with all the tasks, I review the list of priorities to ensure that I have done every task.

The best strategy to do this is to put on protective gear such as gloves to avoid contracting an illness while cleaning restroom facilities.

8. What Is The Biggest Challenge You Foresee In This Job?

The highest challenge I foresee in this role is a high turnover rate. Most people do not consider the janitorial job a long-term occupation. This is because of the nature of the job. It’s easy to get burned out quickly. However, company culture can play a part in retaining its janitors by demonstrating great leadership, paying them well, and offering them training that partakes the job.

When I was new in this career I realized that people had low respect for janitors. The way they would talk to us and treat us. Other employees would keep complaining about undone tasks that were not in our scope yet they expected us to handle. This killed my morale for this work to an extent that I was not proud of being a janitor. My self-esteem and ego went down and before I knew it, I had become depressed. However, during end year staff meeting, I was surprised to be named the best employee of the year and I was given the award and a huge sum of money as an appreciation.  I was happy to know that the management recognized my service even though other staff looked down on me. This taught me to be the best version of myself regardless of what others think or say about me.

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

In my previous role as a janitor, my colleagues voted me in as the best janitor of the year twice in two consecutive years. This made me know that my services were being recognized and appreciated. I believe that working hard pays and can open other doors beyond someone’s expectations. That is why I work with a self-driven attitude even if I am placed in a fast-paced environment. I am now working harder to retain this position.

I always check my cleaning products and supplies so I could restock them in due time to avoid inconveniences. I keep a record of my cleaning products for restocking and accountability purposes. However, if they run out unexpectedly, I would inform my supervisor about it. On the other hand, if the cleaning products require time to be ordered, I would reschedule the cleaning time but instead do other tasks such as vacuuming and sweeping.

16. How Can You Carry Out Your Duties When Other People Are Present?

I will politely inform the people present that I want to clean the equipment or a particular area. However, if I’m required to clean the floor, I will begin by putting out collapsible safety signs. I will also be flexible if any of the people want to use the area. I will allow the person to use the area and ask him or her to inform me when I should return to cleaning that area. In the meantime, I will switch to other tasks as I wait to be called back.

I can also relate well with people regardless of their cultural background and social status.

26. When Children Play On The Area You Just Cleaned, What Will You Do?

It is not uncommon for this to happen. Clean spaces appeal to everyone, especially kids. If this happens again, I will clean the space again. The feeling that I get when I see people enjoying a clean space motivates me. By the way, I love kids as they are very innocent, so frankly, this doesn’t annoy me at all. In my last job, I was doing my work in the park when a kid intentionally started playing at the lace I was cleaning. He wanted to tease me but each time; I was giving smile to him. He realized the same, smiled back, and left.

27. What Will You Do If Someone Violates Your Health And Safety Policies?

I’ll first talk to the coworker and ask that they don’t repeat the mistake.

These issues will be handled as per the company procedures.

I also keep spare tools in case of problems with my usual tools.

I have worked in a group setting for a large organization, and I enjoyed it. It would be convenient to exchange shifts or responsibilities if someone needed to take leave. Additionally, I have experience working independently without supervision. Because I am prepared for any environment, I can survive there.

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

In reporting the matter, I will follow the company’s procedures. My supervisor will be notified of the issue so that the appropriate authorities can be contacted. But this also varies from issue to issue like maybe, the problem is not so big or I a solve the same by myself then why would I bother someone else, I surely will try to come up with the solution myself.

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

I prefer to start my work in empty rooms and public spaces where interruptions are minimal. Having small wins early in my day makes it easier for me to gain momentum. When I reach the occupied areas that require more work, I move on. Then, I move on to the public spaces, which require frequent cleaning to remain in optimal condition.

33. How Do You Clean A Restroom Properly?

To clean a washroom, you need to wear protective gear. Urinals and toilets can then be pre-cleaned. Surfaces can then be cleaned and disinfected. Walls and windows can then be cleaned. Toilet paper can be refilled. You will perform spot checks every hour or two during the day to handle any messes.

34. Have You Ever Dealt With A Customer Complaint?

That’s right, I did. During a customer service call, the client complained about the nature of the service provided. This made me angry. As we are committed to excellence, the client should not judge the organization based on the actions of one individual. They were referred to another customer service professional who was happy to help them. Ultimately, the customer was satisfied. This was unexpected because when he entered the building, I thought it would be the last day of my work.

35. What Is The Best Method For Cleaning Public Areas When People Are Present?

The people passing through the space are prone to destroying the cleaning process from time to time. Signs should be displayed to indicate cleanup is in progress and that the floor is wet and slippery. This will cause people to avoid the area. Public areas sometimes become very messy, especially when there is any event, arty, or public holiday. People keep throwing many wastes even if they are provided with separate bins. Anyways, I never mind the same as I love helping others. This never seems to irritate me.

36. How Have You Experienced Chemical Cleaners?

Several chemicals have been used in my cleaning. For example, I have used chemicals for melting snow. However, since they are toxic, I rarely use them. Moreover, I learned how to mix them properly to avoid any potential hazards from the chemicals. The most important thing while using them is their effects, i.e., what effect they will put on people, especially the kids. So, I choose them all wisely and take great care.

37. When Your Supervisor Wasn’t Around, How Did You Solve A Problem?

Several problems were there, but I solved them all. A washroom developed leaks. As my supervisor was absent, escalating the natter at that time seemed unreasonable since there was nobody to resolve it. My DIY skills helped me temporarily resolve the issue so that customers could use the washrooms. Upon receiving the issue, I escalated it to my supervisor, who found a plumber who could fix it. Later, when my supervisor came to know this all, he not only appreciated me but also assigned me some more tasks, which he thought I could complete in his absence.

38. How Do You Deal With Pressure And Stress At Work As A Janitor?

Under pressure and in challenging environments, I thrive. This motivates me to come up with creative solutions. A demanding environment makes me happy. The physical aspect of the work helps relieve stress during the process. Cleaning is a therapeutic activity. Dealing under pressure sometimes becomes irritating, especially when your colleagues or seniors are not cooperative. This creates real stress in these scenarios.
