The same advice for this applies for all projects! Fundamentall, no 2 projects are the same, and you're really going to have to learn on yourself and others in order to succeed. There's not much we can do here!
This is really going to come down to your grit, determination, ability to ask questions / ask for help from your peers on the role, take guidance, etc.
That being said, here's some general advice.
First: Read the 25 tips in my consulting handbook here: https://www.spencertom.com/2018/01/14/consulting-survival-guide/
1) Understand the context/prompt (what role are you in, what company, who's watching, etc.)
2) Understand the objective (what, specifically, is expected from you...both day to day, and in your overall career progression)
3) Quickly process information, and focus on what's important - Take a lot of information and the unknown, find the most logical path, and focus on that.
4) Be comfortable with the unknown, and learn to brainstorm - think/speak like an expert without being one
In summary, there will always be a flood of information, expectations, competition etc. and not enough time. Find out which ones matter when. (i.e. be visibile and focus efforts on the things that people care about)
