I enjoy Cambridge very much and am grateful for the experience to work in a professional office. The variation of assignments was fantastic so that I wasn't stuck doing the same thing everyday.
What I wish was different
I wish I had more creatively stimulating work... Some of the work assigned to me felt like 'busy work' or I didn't get to see the impact the work I had been doing had on the picture at whole.
Advice
Do not be scared to not know how to do something. It probably has a simple answer and as soon as you learn from someone else, you can apply it to the next time it comes up or educate someone else.
