The email? Today
I legit applied like 1-2 weeks ago
I did the oa sunday
It's trading intern
US
Honestly might as well give it a shot if you haven't applied yet
Shot for swe or whatever you're interested in i mean
Probability theory, 80 in 8, sequences, zap n, personality test
I'd been practicing the mental math section for like a week or two before
The sequences I just did easy, medium, hard on this site
https://www.fibonicci.com/numerical-reasoning/number-sequences-test/#:~:text=Number sequences test example%3A&text=The Fibonacci sequence is without,everywhere%2C from seashells to galaxies.
That was all the practice I did, but the hard section was pretty good for figuring out how some common patterns work
Honestly, I don't really know a lot about natural born vs trained for this
You know that feeling where your mind is rusty and crusty, and you do some small, high school level competitive math problems, and you feel like the rust is wearing off and you feel like you recognize patterns and stuff better
It was like that but when I did the hard quiz on that site
Like I didn't know these patterns before, but as I worked on them, I felt like it was "eye-opening" but instead "mind-opening"
Also, what probably helped the most actually was practing the mental math a lot
Because then you can kinda feel if the terms are arithmetically related or geometrically or neither
I can't really explain it

Because then you can kinda feel if the terms are arithmetically related or geome...
Or some combo

I can't really explain it
But I think if practiced the sequences before the week or two of mental math practice, I wouldn't have done as good
On sequences

Also, what probably helped the most actually was practing the mental math a lot
It's like this is learning some abstract theorem

Like I didn't know these patterns before, but as I worked on them, I felt like i...
And then this was using it on concrete problems which makes you understand it intuitively/fundamentally
Idk, that's the best I can explain it

@meager path if you dont mind me asking how did you prepare for the probability section? I feel like the mental math portion for me wasn't too bad but I got tripped up on the probabilty part
meager path
I didn't prep too much right before since I was confident, but I'd say the green book would help, I read a good chunk of it last semester, and just the random websites with those kinda questions like quantquestions . io and openquant or whatever they are
meager path
I'd say if you've never been exposed to probability theory stuff before college, amc combinatorics & probability problems are probably good enough with the green book to cover everything except expected value
meager path
still reading green book rn it is lowkey super dense
For optiver, at least for the oa, you can skip everything that's not the raw probability section, like stocastics and everything after that, and brainteasers
Wait, you should know how to solve markov chain problems though of course, idk what section that was in
loud wagon
yeah i think in terms of foundation I took most of the classes needed e.g combinatorics, calc, lin alg I prob just need to practice the interview prep
meager path
I guess I mean skip the martingale or whatever section, not stocastics
loud wagon
is your background in math?
meager path
Yeah, math + cs

Thanks, you too
