Since CS is still an emerging specialty, little distinguishes a Customer Success Manager (CSM) from a Customer Success Operations Manager (CS Ops) Manager. Nonetheless, a CSM's primary role is to guide customers through the sales process focusing on value proposition. Customers contact the CSM when they have issues with a product. Consequently, the CSM must have a thorough understanding of the consumer's needs and share this with the product, sales, and marketing teams.
This is generally a senior role, so hiring managers focus on experience and achievements. Demonstrate your expertise in working with customers and any notable achievements.
