Portfolio analytics is not investment and market-driven as it might sound. During the internship, it is up to you to direct your learning and interests.
A skill that will advance you in this environment is technical skills because the job deals a lot of production. If you know a bit of computer science, that's great.
For me. I did not, so I really focus my time on learning and understanding terminologies and market-related issues.
Full time responsibilities can be a lot more tech-based than the summer internship.
Skills from this group might not be transferable to other finance jobs due to the heavy focus on its proprietary production work.
Full time is also a lot more hours than internship - so summer experience doesn't give u a clear idea of what your full time would be like.
