Since it is a formal debriefing in the process of job hunting, it is necessary to explain in detail the problems you encounter at work and the solutions.
Briefly:
First of all, explain when you came to the mall and how long you worked as a floor supervisor in the mall. Thank the leaders of all parties and basically say a set of words.
Secondly, it is necessary to explain clearly the handling methods of some problems you encounter in your work and the experience you have learned. This should be explained in detail in a long paragraph. There should be communication with colleagues, as well as the handling of practical problems in various brand areas, explaining your handling methods. Modesty is ok, but don't be too modest, which will make others think that you are incompetent and not competent enough.
Third, put forward some shortcomings and improvements in my future work, strengthen my study, and strengthen my communication skills with the leaders of shopping malls and merchants.
Finally, regarding the good prospect of the shopping mall being linked with its own development, I express my determination and willingness to dedicate my youth to the shopping mall, and ask the leaders of the shopping mall to review your above-mentioned debriefing report and past work performance.
