Discussion: Which is tougher- getting selected to interview or the actual interviews themselves?

Hi, this is just a question out of curiosity. 

I know typically it is pretty difficult getting shortlisted by the MBBs to interview if you're from a non-target as you'd need stellar results and connections. However, where I am from (in SEA), the BAs are reserved for local graduates and foreign graduates from "better" universities enter at Associate level instead. I would say this makes the process of getting shortlisted considerably easier.

Hence, I was trying to evaluate if the entire process here is easier as compared to other countries. I would say that the case portion of the interview can be practiced and learnt to the point that arguably anyone can do well.

Wanted to hear opinions on this. Thanks!
