When you accept a GLG project invitation, we ask for your availability so we can quickly schedule a call should a client want to move forward. Most GLG projects are time sensitive, and asking experts to provide availability up front allows us to facilitate consultations as quickly as possible. It also ensures that we're aware of and avoid scheduling during times that you're not available.
Even though availability is provided in 30 - 60 minute increments, the actual call time may vary.
