I don't think you have less opportunities, quite the opposite.
There is a lot of demand in the industry for people with your experience. Of course for digital roles, related to the whole digital transformation that every reputable company is undergoing right now.
You have to understand that while companies hire IBM, EY, etc., for digital transformation projects, that doesn't mean that they don't have people within their own ranks working on digital transformation (quite the opposite).
In fact, those clients “grab” people from the consulting firms the whole time because they need so many people for those roles!
They need people to:
- Design and decide on their digital strategy (consultants don't decide for clients)
- Run / implement their internal digital transformation programs (not all transformation is outsourced, and it shouldn't be)
- Be the client-side of teams when they outsource projects to consultants (someone needs to control their work products and direct them)
- Manage the business and day-to-day operations related to that transformation
Given that you have strategy consulting (and digital) background, you can work on the first one. Given that you have digital transformation experience, you can do the other three.
So it is not clear to me why you think you have less opportunities.
