All of the following are must-have soft skills, except:

Product knowledge is essential in sales and marketing as it allows professionals to understand and effectively convey the benefits and features of a product to potential customers. However, it is classified differently than soft skills, which are interpersonal skills that facilitate interaction and collaboration among individuals.

Collaboration, time management, and empathy are all vital soft skills. Collaboration enables individuals to work effectively with teams, time management helps prioritize and complete tasks efficiently, and empathy fosters understanding and connection with customers. These skills contribute significantly to successful interpersonal relations and overall workplace dynamics, which is why one of the options stands out as a more technical requirement rather than a soft skill.
