Ask an executive assistant about the hardest meeting they ever scheduled, and they won't talk about the busiest calendar. They'll tell you about the one that made them stop and stare at the screen.
From the outside, a booked meeting looks simple: one slot on a calendar. The slot only shows the outcome. The trade-offs and unwritten preferences behind it are where the skill lives, and most people never see them.
Here are five kinds of meeting that look easy until you have to schedule one.
The board call that can't move
A fixed meeting turns one decision into several. Whatever it collides with now needs a new home, and each of those meetings has people, priorities and history of its own. The real question is rarely "when is everyone free?" It's "who can we fairly ask to move?"
The 1:1 with someone eight hours ahead
With an eight-hour difference, one person's morning is the other's late afternoon. Very few times work for both, and a good one depends on whose day is being stretched. A great EA knows when to protect their executive's time and when it's fair to give some back.
The CFO whose assistant only answers by email
Booking across companies means working through people. A great EA writes to the assistant, not the CFO, offers a few times that fit the deadline, and books the one that comes back. Then they keep track of the thread for as long as it takes.
The travel day nobody mentioned
Some of the most important facts never make it onto a calendar. An empty Thursday can be anything but empty. EAs catch these because they know the person, not only the schedule.
The three back-to-back interviews with one candidate
This one looks easy until you try it. Three people have to be free in the right order, with no gaps, on a morning that also works for the candidate. If one interviewer moves, the whole sequence has to be rebuilt. The candidate should still get one clear plan.

Tell us yours
We're building ANCI, your AI scheduling agent, for the job EAs actually do. ANCI takes on the coordination, and the judgment stays with you. To get that right, we need to learn from the people who do this every day.
That's why we started the Calendar Tetris Challenge. Tell us what your executive said, what a great EA would do, and why.
