Obviously, technical proficiency is step one, but after that it's important to have interpersonal/people skills. You're constantly communicating and collaborating with people, trying to solve problems together, communicating your concerns or ideas, and approaching people and situations in a way they can understand. You need to be able to relay information in non-technical terms, in the way people can understand it and take actions needed. Oftentimes, there are problems that arise that a group needs to solve and we need to work with each other and communicate the needs of each area to find a solution that's good for the company.
