thank you for sharing your story. The best advice I could get from mentors were not answers, but more questions that helped me in reflecting what I could do better and if something need to be changed. So please find below some questions. Crisis are opportunities for change, but shouldn't become traps, by making the wrong assumptions of what the future could hold for us.
1) Let's assume you make the switch to MBB or another job. Are you aware of what you are going to get and what you are going to loose if you switch your job? Are you ready for that?
2) Let's assume you stay at Accenture. Maybe an internal rotation could help you achieve what you are looking for outside Accenture? I wouldn't bother too much about the number of years you spent in the company, what counts is the competences you have.
3) Are your competences up-to-date with respect to what the job market is looking for? Let's think about MBBs. They are interested more and more about technology and digital transformation projects, if your set of competences matches their requirements, you would be definetly an interesting candidate.
4) Think outside the consulting box. Maybe the corporate world could be also an interesting exit to consider? Are you really passionate about consulting? Is this what you really want to work on for the next 5-10 years? You are still on time to make a strong career change.
5) Are you really interested about managing people? In some other jobs, technical leadership is not necessarily requiring managerial expertise, they are not always correlated. You could become a technical expert and have more time to focus on your job, rather than on managing an increasing number of people.
Let your brain spin around these questions. Don't settle. Keep collecting information and data about what your next move could be. You're on the right discovery path.
