As someone who works in industry, interpersonal skills are very important in order to be successful. Interpersonal skills include verbal communication, listening skills, problem-solving, decision-making, and ect. These are extremely important because a successful engineer is able to listen and get every detail of an issue. They are then able to figure out ways to solve the problem and make a decision as to what the solution may be. Finally, a successful engineer is able to communicate this solution to his or her team members. Most of the time, the task and projects done are a group effort and to insure that it goes smoothly, communication is key. It is vital that you are able to communicate with your group members to get this project or task done. I have worked in retail, in the medical field as a MA, and now as an engineer. And I cannot stress enough that aside from working hard, interpersonal skills have always been the key to success.
