 I decided to become a GSI firstly to challenge myself to try and teach and second because I had the opportunity to teach a course that is aimed at supporting those underrepresented in the field and that's something that I strongly believe in. The most transformational thing was probably the gain in confidence I got from being able to teach and also work on my presentation and communication skills. I've gained a better perspective for myself on kind of future career in terms of academia versus industry and I also gained a closer relationship with the professor that I worked with which is really useful for mentors and potential letters of recommendation. Working with the faculty was interesting because in Discover Computer Science the GSI is the main instructor. I only worked with the faculty member about once a month talking but she was very supportive and it was really great because I think she is a mentor to me now so that was really nice. If you're considering becoming a GSI I would say don't hesitate to apply. I think it's really great experience and you also learn a bit more about yourself along the way.
