Mark Chang
Sr Software Engineer, Uber
My name is Mark. From designing Boeing airframes to the Da Vinci surgical robot mechanisms to launching a billion dollar product and leading a team of 20+ engineers at Uber, I hope that my experiences offer insight into anyone curious about working in technology. I started out my career working as a mechanical engineer and now I’m a senior software engineer at Uber. What I’ve confirmed is that methodological thinking transfers across domains, and that a person’s approach to problem solving is more important than what they know currently. I’ve interviewed and mentored many junior and mid-level engineers and can help answer any questions about what I look for as an interviewer and mentor.
