I was exploring the job-application portal for a particular employer I am very interested in and foolishly decided to see what the application process was like by "starting" an application, assuming that I would stop before submitting the application. However, on the site, it turns out that an inopportunely-named "update profile" button actually submits the application. What's even worse is that there's no way to retract the application on the site.
What can I do mitigate this stupidity, if anything?-- I could e.g. try to e-mail the company and tell them that I accidentally sent them an incomplete application I can't complete right now, but I've learnt that these kinds of inconvenient mistakes only become worse when you notify important people of them. Alternatively, I could e.g. upload a CV and cover letter which make note of this by e.g. stating "application accidentally submitted prematurely; Will update with more accurate information shortly." Nothing I can think of makes me look like anything better than a blundering idiot, however, and HR people generally throw away anything even remotely inconvenient anyway.
