I am working as a working student at a company and I start my obligatory intership next semester at the same company but in a different position. Today my manager approached me and asked that I should write down all the projects I worked at and he also said that I have to make a half hour presentation in my last week about everything that I did and how the company benefited from me.
The problem is that I have no clue how to approach this presentation because I don't want to sound arrogant while presenting.
Also I have a hard time understanding why this presentation is even necessary, since I stop working in this position anyway.
Are these presentations normal?
I work at a technology company and at the moment I mostly write software to automate processes.
