BB ER Off-Cycle Internship Preparation

Hey,

I got the opportunity to do an off-cycle internship in Sell-Side ER at a BB in London. Since, I just completed my degree, I now have about two months to prepare properly for that internship.

What do you think are the most important skills, knowledge, etc I should learn or focus on in order to succeed at the internship and get that FT offer?

I already have experience through two internships in ER but this time I really want to stand out and be as helpful as possible.

Any links, tips, etc are welcome!

Thanks and best regards!
