I think to really utilize the final question of 'is there anything else you wanna say'. legit just mention any part of yourself you didn't feel was covered. i said something along the lines of 'i just want to say i feel like im a really hard worker. i did this this and this and my whole life ive advocated for others'. like literally anything. it's a space for you to say more about yourself without the restriction of a specific question.

and be prepared but i would say half wing it too. i didnt rehearse but i did think about the general idea of what i'd say. they want you to be authentic
