Specific question would have yielded most likely a different answer. I am quite certain it is more than 212 as number of activities is impossible to manage with so a few people.From the Netflix documentary "Drive To Survive" episode 1, Haas TP Guenther Steiner in 2018 (start of season at Melbourne) was asked by Martin Brundle "how many in the team?". 212 was the answer.
Martin responds with "Mercedes have more people on holiday at any one time"!
Big teams (Mercedes, Ferrari) have about 60-100 people in the office. (That includes management.) Haas probably has less, but must have some. (Give them 25.) That does not includes labour such as design, process, etc. count.
Then track side operations require 40 - 60 personnel, add personnel outside paddock and it adds up 80-100 heads in attendance of race events. There you cannot save so 80 for Haas.
So, that's 100 people already, and 112 to go..?
If you itemized activities and allocate some minimum numbers, one will arrive to conclusion that the answer Brundle received was ambiguous, to put it nicely. We do know they get engine, and their sister company does design in Italy, so who knows what that manpower as quoted left out. Car has today over 700,000 components. Keep that in mind.
Just count departments - Legal, Finances, Marketing, Strategy, Design, Production, Logistics, Materials, Track side operations...etc. and you can forget that 212 number, and Brundle should know better, instead letting such misleading information stand.
