I recently applied to a position at Boise State University and was requested to use JotFrom to upload by CV and samples.I uploaded on PDF successfully

I am not sure if I have understood your question correctly.  Was there any issue with the submission?

Please explain your question a bit more in detail and we will try to help you.

We will wait for your response.

I was asked to use JotForm to upload my resume as a candidate for a job. I uploaded my resume in PDF form. I noticed a mistake and re-posted the same document again. My question is: are there now two PDF with the same up there or does JotForm overwrite a file if it has the same name? Thanks for you help...
