Quick bullet points are enough. You don't need to spend more than 3 mins describing your intentions for this role. Bullet points suffice.

Being engaged with the EA community is not a must-have.

None: I’ve heard of EA, but do not engage with EA content or ideas at all

Mild: I’ve engaged with a few articles, videos, podcasts, discussions, events on EA (e.g., reading Doing Good Better or spending ~5 hours on the website of 80,000 Hours)

Moderate: I’ve engaged with multiple articles, videos, podcasts, discussions, or events on effective altruism (e.g., subscribing to the 80,000 Hours podcast or attending regular events at a local group). I sometimes consider the principles of EA when I make decisions about my career or charitable donations.

Considerable: I’ve engaged extensively with EA content (e.g., attending an EA Global conference, applying for career coaching, or organizing an EA meetup). I often consider the principles of EA when I make decisions about my career or charitable donations.

High: I am heavily involved in the EA community, perhaps helping to lead an EA group or working at an EA-aligned organization. I make heavy use of the principles of EA when I make decisions about my career or charitable donations.

If you don't have a video of yourself already, you can easily record one with your smartphone camera talking about an interesting or pleasant experience you had when facilitating or teaching a group. Just upload it, allow anyone access to it, and put the link here.
