Common reasons this signature is rejected

Signing in capital letters.
A file over 20 KB, which is easy to exceed with a phone photo of the page.
A signature done by someone else. SBI says it must be signed only by the applicant.
Uploading the signature in the photo or thumb impression slot. SBI says you will not be allowed to appear in the exam if the images are not in their proper places.
