First rounds are typically "easier"; not the quotes though: each round really has different objectives.
At a very high level, I'd say the test (PST at McK) is here to weed people who can't do math or logic; the first round is here to eliminate folks who can't do the job (hypothesis-driven analysis, insights, summary...).
Once you get to the final round however, the assumption is that you can do the job; at this point, the selection is more about who the best person is: there might be 3 candidates for 1 position; all three can succeed, but only one is "best".
Tactically, the final round will be more about how you interact with people (rapport building), where as the first round is more about how you think through a problem (mechanics).
Note: this is directionally right, not a 100% rule obviously.
Good luck!
