Pivoting out of AM and into Trading; what can I do to maximize my opportunities?

Hi all. A quick background on me; I'm 22 and about to start my first stint in a bank's institutional asset management division. The program is rotational where I spend one year working in the portfolio management side, the next year in the sales side, and the last year being a focus of my choice (OCIO, Liquidity/FI Solutions). While I'm very excited about the program; the pay is below average and AM at a bank just doesn't seem that lucrative compared to the "real" AM houses like Vanguard/Fidelity/Blackrock.

I was looking into trading but realized trading is an extremely broad term. I'm not looking into prop trading, HFT/Algo trading or anything of that sort since they favor people with comp sci or engineering backgrounds. 

I have noticed roles such as S&T, Trading Assistant, FX/FI Trading Analyst, etc pop up on job postings that don't seem to really require someone from an engineering background, and I'm curious in general what I can do this year to really have a chance at getting into the industry.

I graduated from an extreme non-target with a 3.5 GPA so I have my expectations aligned; I've looked into MFE programs but I don't really have the inclination for it. What should be learning as of yesterday to give myself an edge when I try pivoting roles?

I'm still pretty clueless to how "trading" as an industry is really split up, and which opportunities I have a shot at.
