I finished my very first proper internship at an engineering company (HVAC industry) a couple of months ago. I worked in sales support for the sales engineers and filled out project equipment schedules.
I realized late in the internship that I had made some consistent errors in some of the earlier project schedules I was involved in:
- Incorrectly listed heights of air-conditioning(A/C) units to be 100mm lower than actual
- Incorrectly keying in dimensions (length instead of depth) for A/C units
During the initial stages of my internship, I had asked my mentor to check through my work and to correct me for any mistakes but he seemed to have missed out on my mistakes on the dimensions so it probably went unnoticed.
Would it be the right choice to let them know about the mistakes that occurred so many months ago?
I am worried that this would leave a horrible impression of me for letting them know this late. I didn't initially come forward about the errors because I wanted to make a good impression.
In hindsight, I’m afraid I screwed up even more by dragging it out and not letting them know. I’m also afraid that the projects might run into real issues because of my mistakes. I also don't want my mistakes to affect my mentor
