What will it take to succeed?

A candidate with a can-do attitude, a natural curiosity to learn more, seek out problems, propose solutions, and implement them in a fast-paced environment. They must also be able to work under pressure and have a personality that isn’t fazed by dealing directly with users, all whilst managing a support queue at the same time. They will have a hunger to learn and seek out areas for improvements.
