You can only apply for either the Winter, Spring or Summer vac scheme in the same cycle (so one vac scheme per application cycle).
If you apply for the Winter vac scheme, I don’t think you would be able to apply for the Spring or Summer vac schemes in the same cycle.
If you apply for either Spring or Summer, I think you can select both options, or a preference of one of the two and they allocate one of them.
If you apply for the Winter, Spring or Summer vac scheme and are unsuccessful, you are able to apply to the direct TC in the same cycle.
I’m not sure if this will be the case in this cycle but it was for the last one. Best of luck in your
White & Case vac scheme application!
