Good plan. It's not like that number includes vendors, contractors, drivers or anything that could skew the numbers.

Sarcasm doesn’t really help to move a conversation forward.

At some point, you will learn to try to extract signal from imperfect data. It’s a key skill. If you wait for perfect data, you will miss the trends until they are in the rear view mirror.

Unless you believe that there has been a sudden mix shift in vendors vs. employees, the general analysis of churn and hiring still hold. You are only debating the multiplier on numerator and denominator.

Those are less important.

Why not filter the analysis only to profiles with keywords like"engineer" or "operations". Otherwise the analysis is unlikely to be directionally correct.
