I’ve been offered a job and now going through background checks. Except I’ve just realised the CV I submitted has all the dates out by one year. Ie. It says I worked for a company in 2021 - 2022 but it was actually 2020 -2021. I also have a job that was removed from my CV because it wasn’t relevant to the role and I think that’s why all the dates ended up shifting without me realising. How big an issue will this be? I have already emailed HR and they said the referencing company will be in touch if anything is unclear. I feel sick at my own stupidity.
