Approapriate title for my job
I have been working on a Sponsored Research Project during the final year of my M.Tech. The responsibilities were same as that of a Project Assistant. However, I was not working officially, I was working out of interest along with my thesis. I was also not paid for the job (actually, at that time, the experience that I was getting by working in this project was more important to me than the compensation, so I did not demand any money in lieu of my work).
Now I am about to leave my college within few days and need an experience certificate for the same. Could you help me the position that I can write in my experience letter?
I was asked not to write Project Assistant since it was an official post in my Institution and as I have already mentioned, I was working out of interest and not officially. Can you name any other 'position name' that I can have on my experience certificate.
