Where to start? Incoming IB Analyst with no Background in Public Markets

Hi all. I am a senior at a liberal arts college and am starting at one of GS/MS/JPM in an industry coverage group next year.

I have always been interested in public markets but was never a gung-ho HF or die kind of guy. Banking and finance have always been a means to an end for me. I happened to get a banking offer super early and accepted but am realizing that my interests lie in public markets. Can also appreciate that I will learn close to nothing about public markets investing from my analyst stint in banking. 

I have no academic background in finance but I want to learn more about public markets, more specifically, how to come to a "variant" view on a company (which seems like the core of equity investing - please correct me if I am wrong). The goal is to ultimately succeed in HF recruiting when (if) the time comes. 

Seems like the typical advice is to learn by doing a la creating a mock portfolio or actually investing in names I would have conviction in. 

My question is, as someone with no background in public markets, how can I build a foundation to critically read and understand company filings, ER reports, investor presentations, earnings calls, etc and ultimately form a strong, informed opinion around a name?

As of right now, my plan is to read a ton of VIC posts, especially the ones from the likes of Sundheim, read a few of the recent Hindenberg research articles, maybe read Margin of Safety (would appreciate any other recs). Hopefully, this will allow me to understand what goes into a strong pitch and guide my own analysis. 

However, this plan is super arbitrary. I'd appreciate any guidance on reading materials, resources, or even an outline. 

TLDR: No background in public markets, but want to learn how to meaningfully analyze public companies. Any and all suggestions are much appreciated!
