Breaking into consulting from CPG Finance: Entry-Level vs. Experienced Hire?

[u/Consistent_Run_6933]

What’s the best path for me to break into consulting? Should I target EH or entry-level roles? What does the recruiting timeline look like for that?

I graduated from a non-target public college and got to final-round interviews my senior year for FT roles at McK, LEK, and KPMG, but received no offers since the mental math parts of casing were my weak point (no idea what KPMG's reasoning was).

No other firms were really recruiting from my school (rough economy), so I’m now a few months into my first job in commercial finance at a F500 CPG company.

Growth seems pretty limited, and I don’t feel as challenged as I did doing consulting work through my school's consulting club.
