Many strong candidates lose attention in the first ten seconds. The most common mistake is starting with a vague introduction instead of a clear professional identity.
Long scripts are the second issue. If you need more than one minute, your message is not focused enough. Cut details that do not support your target role.
Lighting and audio matter more than expensive equipment. Face a window or use a simple ring light, and record in a quiet room.
Finally, end with purpose. Tell employers what role you want and invite the next step.
