Create a modern mockup of an AI-powered virtual assistant designed to help individuals applying for call center jobs with the initial steps of their application. The interface should be sleek, user-friendly, and professional, featuring a color palette of yellow, white, and black. Include elements like a chat bubble or an interaction panel, where the assistant guides users with prompts such as 'Enter your name,' 'Practice your call script,' or 'Upload your resume.' Ensure the design conveys efficiency and accessibility while maintaining an inviting and helpful atmosphere.
