Having just scheduled my first round interviews, I went over my CV again to prepare for the fit part, and noted a small error in dates on my CV (a summer internship four years ago says Jun-Aug but was in fact Aug-Sept). I've sent this CV to the MBB firms and one other firm thusfar (all of which I've got interviews with in the coming months). Obviously I feel incredibly stupid, but am not sure whether to contact the firms regarding this or not? I am worried it will look very very sloppy (which of course it is), but am also worried that if I do not correct this, it may mean I fail the background check? I am applying for entry level positions in Western European offices.
Many thanks for any advice!
