The main attribute that Tesla employers look for in their employees is without a doubt passion. Not to mitigate that importance of competency, teamwork, communication skills (both written and in person), etc but passion is the key driver to get hired. They are looking for someone that will push past their normal limits because it's something that they care about with their heart. They want to know and be convinced that you live a life to help the world transition into sustainable energy. Why is it for you? You need to answer that question for yourself.
