I’m saying that it is silly to have those roles be in the corporate office of your employer.

AWS ProServe has a 3 month training program for their early career hires and career transitioners. It was all remote.

Even for their more senior roles, they had “AWSome Builder” where you had a two month “project” simulating a real world engagement where you had a mentor and five people from the department acting like stakeholders - CTOs, CFOs, directors etc. This was also remote where you had to do presentations.
