think i ruined my interview

I recently completed the ao home office interview and does anyone else feel like they completely ruined it (a)I think the behaviours went fine i think i stumbled a bit on one but kept eye contact and made sure i was clear but that's normal but i went absolutely blank on the first strength question as i didn't know what was gonna happen or anything and i sort of went into panic mode and tried to give an answer but there was a lot of stumbling however i tried to use up the 2 mins but it was a shitshow but the 3 other strengths i think i did well on as i took a few minutes to compose myself and knew what was gonna happen i.e five seconds and then 2 mins and and i filled up the whole 2 mins but i just wanna know how everyone else did and if anyone knows how it's marked?
