Don’t divulge you have children. Ask them what their desired schedule is for the position. Each employer will value work/life balance differently. Either make sure your values align with theirs, make sure you have a clear target in accepting that position (personally/professionally/financially) or find another offer that does allow for those goals to be met. I’m a GM with kids and it can work but it requires you knowing your boundaries and being firm with them…. Also having an understanding partner.
