I am currently doing a 1 year masters in the UK and am sending off applications for Consultancy. During my undergrad, I did a 1 year internship at a big name consumer goods company (think P&G, Unilever, Nestle, Johnson&Johnson) in a product supply role. During my internship, I did not enjoy it whatsoever, and my overall performance was mediocre. My manager wasn't happy with me but I didn't get fired as I wasn't terrible either. Obviously I didn't get a return offer.
I am now worried if whatever company I am applying for will contact my previous employer and ask them about my performance and whether or not I got a return offer. Will they ask for a reference or anything? What can I do about such situation? Should I be honest and tell them I didnt get a return offer. I'm worried if they contact my previous manager and he tells them I was "poor".
Any advice will be appreciated
