No-one good is going to do a takehome just so the hiring team can rub their beards and feel superior while they pick over the code. That approach worked a few years ago, in today's recruitment bear market you don't pick the candidates, the candidates will pick you.
We are having precisely the same trouble as you by the way - junior-heavy, but experienced folk are extremely thin on the ground, and we go from CV to offer within a week. One chap joined (for a few days) and left because he had started somewhere else at the same time - they won out. We're moving to 1-stage interviews, offer on the same day. Higher risk but we have no choice.
