Applications will always conclude with your signature. This is where you will certify that you have reviewed all of the information you have provided and that it is correct to the best of your knowledge.
Online applications will ask for your electronic signature. Most commonly this will simply require you to type your full name and the date; however, some companies may have their own standards for the signature and will provide instructions for how it should be completed.
In print, you will simply be asked to sign your full legal name and to print the date.
