Hey there,
Am sorry to hear about the instability.
To your question: It could have an indirect impact on the process. MBB hiring is based on a simple demand forecast. If the business is expected to grow, new consultants are needed, hiring is ramped up, and vice versa.
Now, instability could introduce business uncertainty, which in turn could negatively impact the demand for consultants and freeze recruiting.
On the plus side, McKinsey's global director of recruiting said yesterday that they want to hire more people in 2021 than in any year before so there is definitely demand, which might also spread across countries (just because you are hired in country A does not mean you can't be on an engagement in country B)
All the best to you!
Cheers,
Florian
