Regretfully, after submitting your application, you will not be able to alter the document you have uploaded. We can, however, upload a new, updated attachment (a resume and cover letter combined into one file) and remove the old one, but if the hiring process is already underway, there’s no assurance the hiring team will notice the change. However, if you’re having trouble with the online application process, you have other choices. You might want to use the company’s professional networking sites, social media pages, or in-person applications. Speaking with recruiters or employees directly might also be helpful.
