No direct experience here, but the parallel/experienced hire process is similar across professions. It’s best to have “internal champions” – those within your target firm that forward your resume to recruiters internally, write positive recommendations, help get the ball rolling. Headhunters play a role – but less so in management consulting than in private equity/hedge funds. Reach out to your extended network and generate contacts. Talk to peers/colleagues that have made similar transitions. And keep me posted as this is one area I need to understand better and share with readers.
