I currently have an entry-level MBB offer and am going through background check processes.
One of the experiences on my CV (which I've listed in the application as an internship) was essentially an unpaid co-curricular project that I did with an employer as a part of my degree program. The project involved working on a real business problem with the corporate team, while also being graded by the academic team at my university.
The issue is that I was not paid by the employer, nor was I technically an 'employee' in the sense of being a part of their payroll/HR systems etc. However, the work experience itself is of course real, and I do have proof through various emails, meeting invites, as well as presentations etc. that I built during that time. I also have the actual grade provided to me by the university for completing this work.
Would it be an issue if the employer is not able to verify me as an employee if asked? If so, what would be my best recourse?
