How to solve quant puzzles

[@CodingJesus]

Have you attempted the 1x1 Rubik's Cube?

[@galaxyw5545]

too hard

[@curious_one1156]

Do JS Recruiters look at the leaderboard ?

[@ansgarjohann99]

I have high respect for people competent enough to be consistent with learning these types of things

[@tonywims8848]

Criminally underrated content. This isn't just good for quants. It's great for anyone with the need to solve problems.

[@shubhojoysinha6603]

I have a quant trader internship interview with Jane street on 27th, this should be helpful

[@emmanuelsekyi4166]

did it help?

[@atharvjoshi6701]

How did it go ?

[@Shaktobengalee]

Hey Shubho, hope You got the job & might refer me some resources & specific skillset for the job

[@namanmehta8692]

Hey, please share experience and resources for prep

[@k999ford]

Pfff I can tell you from experience that this is not that helpful for first round

[@Drone256]

There is one major caveat to puzzles like this: It channels thinking patterns into a subset of real world problems. People who make/solve these types of puzzles are repeating patterns whether they realize it or not. Quantitative trading opportunities in the real world requires a broader set of problem solving skills. In every technical field the seemingly smartest people often spend all their energy competing in that field's generally accepted metrics of success. This is why it often appears that earning money is just dumb luck. It's because money isn't earned by finding a niche and then proving to people how smart you are. That may get you a well paying job but it won't solve the kinds of problems that make you wealthy (such as trading strategies).

Where did he end up? His discord link doesn’t work and he doesn’t publishes any videos since 2022. Does anyone knows why? What happened?

[@anamariawil1]

He’s back now lmao, must have seen your comment

[@CalBruin]

The takeaway I get are (a) recognize and use your skill set and (b) ask for help when taking a problem outside your ability.

[@sherlockhobbes423]

Don’t stop w the memes bro they’re great

[@fabspark1631]

How do I get started with this domain...... quantitative trading.....Can anyone suggest some quality beginner friendly resources please..... I'm really really interested 🥺💜

[@dhrumpelstiltskin]

Awesome video!! Circle Time was my first Jane Street puzzle!! I loved the problem so much that I even wrote about it lol. I opted for a math approach, but there was an even better math approach than mine lol (I had an annoying quartic but there was a really nice trig solution). It's cool to see a different (more cs-y than math) approach!

[@adityasinha3851]

Hi, I am currently a third year undergrad and an aspiring quant. I have recently come across your channel and have found the contents interesting. I sat for Goldman Sachs and JP Morgan during my college internship drive for quant roles but ended up failing GS in the quant interview(where they asked puzzles) and JP Morgan in the Mathematics aptitude test on Probab and Stats. I have good knowledge of Data structures and Algorithms and have cracked other companies for SWE role but I want to become a quantitative analyst/researcher/trader in future. Could you tell me about the math, CS and other finance related courses that are needed to ace the interviews and get into these investment Banks and other financial institutions like HFT's. Also, could you tell me about more puzzle resources (like the Jane Street archive) from where I can practice ?

[@AryanSharma-my5lg]

hi Aditya I am a 2nd year student and an aspiring quant , but unlike you I know very less about the field and the pre requsites to get an internship / start a career in quantitative analysis/research ...could you send your linkdin profile so that we can connect and maybe with your help I can also learn about this field and other things

Do Jane Street recruiters look at the leaderboard ?

[@christcombiccombichrist2651]

Finally I got to finish the trading Engine Server series part 1 video. It took me 6 attempt to get I right. But I still don't under those code and their function yet.👍

[@CodingJesus]

That’s why it took you 6 attempts. Study up on C# first.

[@tochinwa1234]

What do you think of Java? In my experience, it is more prominent than C# in the financial services space hence I am surprised you prefer Python, C# in particular. Thanks.

[@robalexnat]

This video is my new favorite drinking game everytime @Coding Jesus says the word "toolkit". Fr, great video!

[@JJ-cq9hj]

Thanks Dude! I learned something new today

[@dr.merlot1532]

When does Jane Street update the leader board? How do I know if my solution failed?

[@CodingJesus]

Once a day. Just keep an eye on the last person on the leaderboards name before you submit a solution and if there is another update and your name isn’t there, your solution failed.

[@twinkleRamalingam]

hello coding jesus, can u make a video on quant developer work life, and how do they manage their time and work and mainly there married life Please make a short detailed video on it, it would be very beneficial for many people around the world , Thank you

[@s7manth]

Absolutely amazing stuff! Respect from Singapore

Liked the content but very poor editing job idk why the editor chose to make this more memy and giving unnecessary music and overlaps though I liked the content as usual

[@Biggyweezer69]

This is just a math problem: Define a ring is circles by the hexagon they lie on, then a hexagon of side length r will have circles with radius r/2. Notice that to fit a second ring inside of a first one, we simply rotate the first one and scale the side length by some constant p. Then notice that the second ring fits perfectly if and only if the distance between an arbitrary vertex of the second ring and the closest vertex of the first ring is r/2+rp/2 (you can verify this visually looking at the circles of the rings). Once can orient the rings conveniently and use coordinate plane geometry to arrive at p = (2/3)*(sqrt3 + 1/2 - sqrt(1+sqrt3)). We can then use a geometric series to find that the area of all infinitely many rings withing a circle of radius 3 is 6*pi / (1-p^2), the percentage of the circle covered would be 2 / 3*(1-p^2) or about 78.35% coverage.

[@manswind3417]

Bro? Just rotate the hexagon by 30 degrees or so, should yield a GP sum. Rectangular coordinates don't appear helpful here.

[@Biggyweezer69]

@@manswind3417 Hahaha lol yeah I must've been on some shit when I wrote that. I'll update my comment with the correct answer, granted I don't see a straightforward way to calculate the common ratio using geometry alone so I'll still be using rectangular.

The music in background is so annoying lol

[@hackerbuoyyy]

Solving puzzles at the comfort of home and under pressure like during interview are totally different things.

[@mrdev5281]

1 L@@K at that list of people 3:34 who solved the puzzle and i see about 60 not 30-50 so i paused the video and counted the first row. You were not even close using 30 so a few of us can see there's weakness in your game theory. Practice that awareness by solving # pieces in a jar.

[@metamoney7657]

I love the video about the books

[@CalBruin]

American education has a skill based focus because that is testable especially using a narrow choice format. American mathematics education is reciepe based; the practice is about teaching very specific algorithms for addressing very specific types of problems but those algorithms are broad enough that can be applied to a wide range of common scenarios. Key words are 'common' and 'wide ranging'.. The discovery approach to maths pedagogy takes too long, there is too much variation between individual pupils, and such problems are too niche to be applicable to larger context or scenarios.

[@codygoss1144]

I want to have a conversation with the people who tried the 1 by 1 rubix cube …

[@CodingJesus]

Some people have been struggling with it for a while.

[@crittercel]

thank you for your service

[@puszkatech]

Jesus I will tell u smth. Do not add music to your videos thinking that, it will extend your retention. It does not, opposite is true. I know because I use to add music to all my videos and now i just left plain talk. Music in this video is to loud (if u want to add one adjust to at least -30db), second it makes u sound unprofessional.

[@CodingJesus]

Thanks for the feedback, I will definitely keep this in mind for future videos.

[@Ritwik_Kumar]

Your name is Tomer?

[@jackcapital7426]

Was wondering what's his name 😅

[@spinLOL533]

Can’t you just use CNNs to solve this?

[@lbgstzockt8493]

Yes, but thats not in the spirit of the question and probably much slower than the right solution

[@Sum_Ting_Wong]

Bro I swear I thought you were Pakistani until you revealed your name 🤣🤣🤣

[@EigenVector22]

Cube

[@CalBruin]

Giving a problem impossible for one to solve is sadistic. When the joke or math problem involving a mad scientist presenting an unrealistic scenario, recall this example. Surrendering on tackling a problem is reasonable. Now, there is a difference between _knowing_ that one should be able to solve a problem, which thet might be able to solve, verses tackling a problem one believes is possible for them, even at their level, to solve. By example, the Goat Problem. (Just so happens I watched a Numberphile video on the Goat Problem. Go watch the video.) The problem is simple and accessible to anyone with high school level of math but the solution requires knowledge of Complex Analysis. Like Fermat's Last Theorem easy to state but proving requires advanced high level mathematical knowledge.

Why 110? Seems kinda weird number but I’d say closer to 140
