I liked seeing the change I made in real time. I helped with projects that had a positive effect on the world. If you did not understand something there was always someone there who was knowledgeable about your question and able to help you find resources to successfully accomplish your goals and tasks. AnChain.AI cares about their intern's learning necessary skills for the field. They have a great work environment.
What I wish was different
I don't think there is much I would change. If anything I wish the internship lasted longer.
