I submitted an application yesterday for a marketing position at a tech company, but I just realized that I attached the wrong cover letter—one meant for a different job. I received an automated email from HR confirming they got my application, but now I'm worried. Should I submit my application again with the correct cover letter? I've heard mixed opinions on this; some say it's better not to resubmit and just hope they overlook the mistake, while others suggest that any error like this could hurt my chances. I'm feeling anxious about this situation.
