What I liked
I was given very interesting projects where I was able to use my math background and build my tech/coding skills. Had an awesome team that included me in every meeting, global or local, and were all incredibly smart human beings that I enjoyed spending long days with. In addition, they were very helpful in answering my 1000+ questions. Also what I really appreciated was having a "buddy" (every intern is assigned one), who is there for work/non-work related concerns, but what I took away from having a buddy was going to someone that you feel more comfortable and safe with when asking (perhaps a stupid/risky) question.
