Same considerations and hurdles - international firms are not going to want to re-train you, so will take you at a PQE cut (or not take you on at all). Unfortunately, DPP experience simply doesn't transfer across to corporate law.

You could try for liti roles (arbitration or white collar / investigations) with international firms, but there are often many suitable applicants for a very small number of roles. And you'd be up against liti ppl from B4 firms who probably have more directly relevant experience.

B4 will consider you for liti roles, and MAY consider you for corp roles (possibly with PQE cut), so this is definitely one way to get your foot in the door. But you'd also have to consider how much energy you have to re-train as a junior corp lawyer.
