I join when the meeting reminder pops up and I click "join", right on time. I don't like small talk, no point in being early.

Usually as soon as Teams notifies me of the first person starting the meeting.

How can you not always be the first when youre 5min early, wtf xD

On the dot if I can.

I join at exactly the designated time. If you wanted me there five minutes earlier, then schedule the meeting five minutes earlier. Don't jerk me around with some expectation that I'm going to do anything other than what you asked for. Also, most of the folks I work with tend to be booked with lots of back to back meetings; so, no one is showing up early anyway. We all show up at the designated time and anyone late can catch up when they show up.

The "early is on time" mentality makes some sense for physical meetings and appointments. For virtual meetings, it just demonstrates that the person has no understanding of how technology works.

On time, even when presenting. Starting early makes other people feel obligated to join early, so I don't do it. No reason to extend the meeting longer than the listed time.

One to two minutes late to most meetings. I don't have time or energy for the BS of "How are you" etc. Let's get down to business.

Caveat is that if it's with a VIP I'll be exactly on time.
