I’m currently in the background check process and realized that my months on my resume for my jobs are off by 1 month each due to me assuming the start date was the day I signed the offer letters (dumb, I know) .. The information I put on my background check info was correct but the resume is off by a month on two jobs. Will I have a chance to explain myself? Will they question me? Has anyone had this experience?
