how do you determine or scale (her) in less than 5 minutes?

my go-to line is what they do, usually tells me what kind of lifestyle they go for... "you look like you work in business, the way you dress" or just simply "what do you do?"

somehow horoscope is hot right now but i can usually use it to also see if she's, for example, single "taurus usually r single people" but I sometimes dont have time to memorize all the signs, so I just end up fumbling and shitting on the open (which sucks)

i dont like to judge by the cover because ive been taught to treat others how you'd treat them, but it's also not that hard to distinguish a low-key girl vs. a high maintenance type by the way they dress: jeans on a high-casual type venue BUT then, I do get it wrong 50-60% of the time

so I either just ask her what she does, and then I just go straight to entertainment, do you have netflix, do you like watching films alone

Is it even possible to know key facts in the first 5 minutes? I just don't want to waste both of our times especially on a public non-acquaintance event
