Any big 4 early career switchers have advice to share?

Am the poster few posts back who asked about getting into big 4
Local uni grad, couple of years of corp acc and Biz experience

Thinking of getting into the big 4 for foundation building but so far no news at all
On the other hand, recruiters and LLEs/MNCs have been approaching me, but I have mostly declined because of the big 4 dream

Any advice
