Which technicals should I know for IB interviews?

I have the "The 400 Investment Banking Interview Questions & Answers You Need to Know" study guide, and I was wondering which technicals to really know for interviews/superdays. I know the guide breaks them down into basic/advanced versions, and has several different categories of technicals (accounting, EV, DCF, LBO, etc.). Should I memorize all of them or are there certain categories that I should focus on more?

Also, this would be for 2021 summer analyst programs if that makes a difference (vs. someone who's already out of college/has some experience).

Thanks!

don't memorize all of M&I 400 but rather understand all of it. How much you "should" know entirely depends on the firm and your interviewers – which is why its best to just know as much as you can to have your bases covered. I emphasize "understand" because many questions asked by interviewers have follow ups and "off the guide" variations that truly test if you know what your talking about. As such, I typically would suggest something foundational before touching the guides, like Rosenbaum & Pearl. However, seeing that time is a bit constrained for SA 21, I'd suggest that you go through the M&I 400, but really really try to understand concepts as you go

 

So far accounting and valuation are the ones I've been asked the most. I've gotten some fairly easy questions from an EB, but tougher questions from a BB. Through my post-interview self-review, I was able to find most of the answers in the 400Q guide.

Knowing 400Q guide in and out will help you pass the baseline technical sanity check.

 

What is a good next step for prep after you've built an understanding of Rosenbaum and 400 questions guide?

 

In terms of priority I’d say 1) 400qs 2)BIWS 3)rosenbaum/damadoran/free online material

Damadorans work is great (and free). I bought the rosenbaum book too but thought it was pretty barebones - there’s a ton of great free resources online that can give you a similar breakdown in terms of modeling (see macabus).

Last but not least make sure to get the 400qs down in its entirety. You should be able to get by most interviews with this knowledge. I think is also free if you look hard enough online.
