The similarities in my experience between big tech (FAANG) and big non-tech are heavy process/communication burden, deep tech debt and perf review driven culture.

The main differences in tech are:

Engineers seen profit centers instead of cost centers, therefore treated/compensated as "talent"

Many (but probably not most) big techs are bottom up, much less common in non-tech

There is at least as big of a process and cultural difference between small startups and big co's.
