Being hired in as an engineering manager requires having been an engineering manager previously (at any company), generally for a reasonable period (let's say, minimum two years of full-time management experience minimum with at least 3 direct reports), with a career YOE of around at least five years. You're generally coming in at the same pay band as a senior IC (you might be able to see this sort of information in levels.fyi), so you'll be in the same ballpark of experience/career trajectory.

If you don't have enough engineering manager experience, you can generally join as an IC (with a full IC interview loop) with a view to converting to manager. You may have additional discussions or even interviews around management as well, especially if converting to manager is something you identify as a career goal (as opposed to an option).

Converting to manager from an IC is generally pretty easy if you've shown good aptitude for leadership - the larger companies generally find it a lot easier to hire ICs than good managers externally, so internal conversions are necessary to keep up with demand for quality management attention on teams.
