Private Banking Interview Prep (BofA/Citi/JPMC/Santander/HSBC)

TL;DR : Need to know what to study/prep for private banking interviews (Yes, I know these are usually simpler but I'm in the middle of a career pivot and absolutely need to CRUSH these)

Hello Monkeys, hopefully this thread gets some traction as the information I've received everywhere has been as general as can be. Graduating senior at semi-target with heavy (as can be for a senior) consulting experience (M&A Advisory, foreign investment, etc.) I have recently decided to pivot towards Private Banking, Wealth Management, and Asset Management. Yes I have done my research on the differences between each career path, and am completely impartial on those as all possible outcomes interest me heavily (unless I go the WM route and don't make it as an FA in 5+ years, in that case the thought of only having the transferrable skill of financial product sales scares me). 

I have a few interviews at the banks on thread title, and I absolutely need to crush them, and plan to do so by preparing as best as I can. The reason behind the importance is that I have an offer for the consulting shop I worked at this summer on the transaction advisory team, and luckily, I have more time than usually given to accept the FT offer, and since these are the only interviews I have in that time span, I need to maximize my probabilities of receiving offers. If I don't get an offer, I will have to accept the consulting offer, as rolling the dice in this job market is probably not the smartest in my position. 

Appreciate all the help!
