The designer interview process typically involves three rounds of interviews. The first round usually involves a meeting with a product manager, who assesses the candidate's understanding of product design and their ability to communicate design concepts. The second round is with the CEO, who evaluates the candidate's overall experience, design philosophy, and ability to contribute to the company's goals. The final round is a technical interview with a developer, which focuses on the candidate's technical skills, design software knowledge, and ability to work with cross-functional teams. Throughout the process, the candidate is given the opportunity to showcase their portfolio and discuss their previous work experience.
