Background check

Hello, I did a first year in an unknown University and I transfer into a good uni now. There are some courses I did in the first uni so I validate this courses from the unknown uni to the bachelor of the good uni. I have an internship in Bain&company but I omissed my first year in the other uni. I don’t know if it is a huge problem. I did 1 year in the first and now enrolled 3 years in the second
