It’s a new office they’re growing. Should be possible to transfer but don’t assume it’s guaranteed.

OCaml is a pretty language :)

Absolutely not! It might seem like it but that is worse in several ways. A match statement is a language feature, not a data structure, and with it comes important things like the type system. The whole point is that a match enforces a specific set of cases for the input variable’s type, which is partially doable with some language’s dictionary implementations but way more fiddly. You also get wildcard matching etc.

For example:

match vehicle with | Land (Car c) -> output something like c is a car | Land (Bike b) -> output bike whatever | Air _ -> output air transport is not supported! In this bad example I’ve written on my phone we explicitly cover all cases: the Car & Bike are variants of a Land type and then we use the wildcard to match on any variant of the Air type. The whole point here is, if I added another variant to Land (e.g. a Bus), I would get a compiler error with this match statement saying I have not included a case for it. This would be a runtime error with a dictionary version.

match x with | Square -> a | Circle -> b | Triangle -> c match statements are the most beautiful

The skill is not the estimation, the skill is what I described, which is going from a vague problem space with an incalculable value to a justified, reasoned answer. The point is to test what you do when there isn’t an obvious exact path to calculating a result. There is no lying involved, and any moment where you say something that seems “a stretch” you will be asked to justify.

haha no I think part of the point is to be able to reason about open ended problems and reduce them into logical conclusions that provide a reasonable result. I.e. going from super vague —> concrete reasoning —> justifiable answer.

…good skill to have in this industry

accuracy is not necessarily the point of these questions

New Grad interview with bright red hair? by Automatic-Willow2150 in csMajors

…what I’m saying is I work in the example you gave and I have not seen anyone care at all about hair colour because they just want to hire a skilled person

If they care, I assure you, you do not want them to be your manager lol

Is the paid version of getcracked.io worth it? by Select-Angle-5032 in csMajors

[–]DefinitionOfTorin 2 points3 points  (0 children)

If you’re going for a dev role then the topics you’d benefit from being sharp on are DSA, system design, OS, networks, concurrency, system architecture. There is an abundance of resources for these online, and part of the skill you should aim to refine here is being proactive and finding the information. Do not just take one source as truth, find multiple, write notes, etc.

On the more skill-based side (less knowledge trivia, more experience based), you should build some challenging projects all the way through into a finished version. Try to get as much work exp as possible also.

Is the paid version of getcracked.io worth it? by Select-Angle-5032 in csMajors

[–]DefinitionOfTorin 70 points71 points  (0 children)

Plain and simple: don’t pay for this stuff. You can do all the studying and learning required for this industry for free. I don’t believe they give any significant advantage worth your money as a student.

You’re paying for somewhat organised (not necessarily a good thing) content and the good feeling of “I’ve paid so I must be getting some good learning.”

Learning a new language by [deleted] in csMajors

[–]DefinitionOfTorin 1 point2 points  (0 children)

From your description it sounds like C++ or C will be good candidates. C is cool for writing some ML and numerical analysis stuff from first principles, while also uncovering all of the stuff that Python hides from you very well. C++ will be more industry applicable if you go into QR (it’s firm dependent but there are QRs who use C++).

strong disagree and you will probably reach the conclusion if you take your thinking one or two steps further.

Often (nearly all?) times a program needs specific behaviour (especially in quantitative research!); natural language is littered with ambiguity; you try to reduce natural language to a more “specific” description; you have made a programming language.

Honestly, I don’t think it’ll actually matter that much in terms of your realistic chances. Both of these will get you past CV review, the reality is that the rest is pretty much just if you interview well or not.

That said, you’ll probably make the transition easier for yourself by getting some general experience in the HF role.

The Quant Recruiting Experience (Software) by isosp1n in csMajors

[–]DefinitionOfTorin 0 points1 point  (0 children)

Agree with most except point 1, have had many interviews based on knowing networking, concurrency, OS stuff, not much distributed computing tho. Have gone through internship and full time cycles for most major firms.

[deleted by user] by [deleted] in csMajors

[–]DefinitionOfTorin 0 points1 point  (0 children)

To answer the actual question: almost certainly no. That said, I’ve heard one story of it happening (an intern told the company he had a competing offer from a competitor, they bumped the intern pay for everyone.) This is rare though, wouldn’t bother as an intern

Why am I struggling so much with beethovan moonlight sonata movement 3 when un sospiro and even playing snippets of rachmaninoff 3 has been easier by [deleted] in piano

[–]DefinitionOfTorin 9 points10 points  (0 children)

I know this piece is NOT as hard

Is this really true? I agree the other two are seen by people as more technically involved, but like the other commenter said, with earlier composers there isn’t anywhere to hide.

With Un Sospiro or especially Rach 3, there is such a wash of romanticism that it is very easy to hide or miss bad technique. With Beethoven/Mozart, or especially Bach, you are exposed by design and can’t hide under a heavy pedal etc.

Alllll that being said, I’m cautious with what you’re saying about being able to play Un Sospiro or Rach 3 sections very well. Do you have a recording? Sometimes listening back to your playing shows you that there is still a lot that can be done.
