Critical Rejection Warnings
- Never use ALL CAPS: Signing as "RAM KUMAR" instead of "Ram Kumar" will get you disqualified instantly.
- Avoid dark backgrounds: Do not take a photo of your signature in a dark room. Sign on a pure white, unlined sheet of paper in bright daylight.
- No overlapping text: Ensure your signature does not cross any printed lines on the paper.
