After assessing the situation, I decided that it would be best to divide the tasks among my staff so that each person could focus on one specific area. This allowed us to work more efficiently and complete the job within the allotted time frame while also ensuring that all areas were cleaned properly.

My decision required me to delegate responsibilities and trust my staff to do their jobs correctly. It was a difficult decision to make because I wanted to ensure that the job was done right, but I also knew that if I didn’t act quickly, we wouldn’t meet our deadline. In the end, my decision paid off and we completed the job successfully.”

20. What do you think is the most important thing for a janitorial supervisor to keep in mind?

This question can help the interviewer get to know you better and understand what your priorities are as a supervisor. Your answer should reflect your understanding of the role of a janitorial supervisor, including how it differs from that of an individual janitor.

Finally, I would provide them with an opportunity to correct their behavior and ensure that they understood the expectations going forward.

I also believe in being open and honest when communicating with my staff. This helps to build trust and respect between us, which is essential for any successful team.

As a Janitorial Supervisor, I make sure to communicate regularly with my team in order to ensure that everyone is on the same page. I also provide detailed instructions for each task and set up regular check-ins to review progress and answer any questions they may have. Furthermore, I use performance reviews to evaluate how well each individual is meeting the standards of the job. This helps me identify areas where additional training or support may be needed. Finally, I always strive to create an environment of trust and respect so that janitors feel comfortable coming to me with any issues or concerns they may have.”

The building had just gone through a major renovation and there were new areas that needed to be cleaned. In order to meet the needs of the new layout, I had to create an entirely new cleaning schedule and assign tasks accordingly.

To do this, I first consulted with the building manager to get a better understanding of the changes and what would need to be done. After getting an overview of the situation, I created a plan that included assigning different tasks to each team member based on their experience and skill level. This allowed us to complete the job efficiently while still meeting all of the necessary standards. Finally, I made sure to communicate the new plan to everyone involved so that they could understand the expectations.”
