I think Robi’s point still holds, because the statement in the post, “at the beginning of their careers, are contemplating a career shift [...], or have accumulated several years of experience,” arguably doesn’t include very senior people (i.e., people with many years of experience, where many > several).
I think if someone has accumulated many years they have also accumulated several years.
[I’m being very pedantic here, sorry.]
