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!

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

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.

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).

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

@CodingJesus 2 жыл бұрын

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.

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 ?

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.

I don't understand how the ring problem is a coding question, isn't solvable with just math? Edit: I tried using coordinate plane geometry and to find the explicit radius of the circles in the second optimal ring you need to solve a degree 8 polynomial that is not conveniently reducible by any means. While much more complicated and requiring more math knowledge than solving with code alone I think that getting to the point that I got and then using code to approximate the solution with numerical methods would probably have the fastest runtime.

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.

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.

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.
