Each mentee is different, so their needs and expectations aren't always the same either. Generally, the mentee does not have the necessary tools to succeed in the job search. You help the mentee make a plan for the future. Some mentees already know very well what kind of work they want to do. For example, you can help you find the right company, with the resume and cover letter, and apply.
Other mentees still don't know what kind of work they want or can do. In that case, you will figure this out together. It is also possible that you will assist you in making a choice of study.
