A job posting closed while I was filling out my online application. I saved a draft of the application because I was waiting for a letter of recommendation from my previous boss.
When I picked up where I left off, I discovered the posting was no longer available. The deadline for the job posting wasn't visible.
I have already applied to other jobs, but there might be a very slim chance with this one. I still have my draft and it includes the job posting title and job number. With this information, what is the best way to contact HR about the job posting?
