Keep in mind this is an advertised position (and multiple different positions were in the ad) so they'll probably get dozens if not more resumes

Sending off an application and in the subject line somehow accidentally spelling Engineer "Enginer" and hoping it's ignored with them only noticing the ref # in the subject and my cover letter and resume is just forwarded on through the proper channels.

A couple weeks later, resending the same application but spelling it right this time, changing the wording of the subject line a bit so it just looks like I applied twice without realizing it, but they may not even notice due to the volume of applicants?
