Been there, done that. Everyday would start with a 2 hour session of meetings. Daily for 30mins and then 1.5h of refinement. Day by day, for 2 years of me being there.

It, without an ounce of irony, leaves a fucking scar on you and makes you despise having meeting for the rest of your life.

I remember working in the office and the customer visited and took part in our task estimation meeting. We've spent about 3 hours in one block estimating their tasks because they had so much input.
