An account executive is a good career choice for someone who likes sales and managing client relationships and wants to grow accounts for their organization.
Day-to-day tasks could include emails and calls with clients, cold calling to find new clients, and dealing with client needs as they arise. Seasoned account executives will learn how to pitch clients and how to follow a sales cycle from hunting for a new client to closing them.
Account executives can make good salaries. Typically, they are paid a base salary along with sales commissions or bonuses for bringing in new business.
Whether it's a good career for an individual will depend on their skills and personality, but working as an account executive is a common stepping stone for people who work in sales or a related area.
