Sales engineers are responsible for pitching the technology or service of a company to possible buyers. Products need to be sold based on their performance and abilities and a sales engineer must be capable of conveying these qualities effectively to buyers. Interviews will feature various sales scenarios and test your ability to sell the type of product employers are offering.
