I enjoyed learning about a variety of different CAD tools, designing for manufacturability, manufacturing workflow & processes, and also learning from a lot of the machinists and their experiences as well. As an engineer, understanding these processes are invaluable, and make you a much more competent, well-rounded, thorough engineer, especially from a design and quality standpoint.
What I wish was different
It would've been great to obtain a little more sophisticated training at the start, but overall, without a doubt I learned A LOT from this internship.
Advice
Always come in with a positive mindset, be willing to learn and work in a fast paced environment, and hone your attention to detail. These skills are extremely valuable in any industry, but especially in this position, and as an engineer overall.
