  • The amount of CPU time compiling code is usually negligible compared to CPU time at runtime. Your comparison only really works if you are comparing against something like Rust, where less bugs are introduced due to certain guarantees by the language.

    Regarding “language constructs” it really depends on what you mean. For example using numpy in python is kind of cheating because numpy is implemented in C. However using something like the algorithm libraries in Rust woulf be considered fair game since they are likely written in Rust itself.











  • FYI, leetcode is not a “learn to code” website it is a “practice problems that will be asked at tech interviews” site. A lot of these problems are inspired by (or maybe are even literally from) interviews at “top companies” like Google, Facebook, etc. They are almost completely algorithmic or data structure problems, i.e. “unrelated to your actual work” (well, most of your actual work for most people).


  • Wouldn’t you argue that putting hard restrictions would have the benefit of shrinkjng your recruitment team? To be clear, I’m coming from an extremely anecdotal point of view, but to me it seems like tech is full of imposters jumping from job to job, playing up their experience. Recruiters cannot spot these people, because they know all the jargon despite having none of the skills. This is why these technical interviews exist, but now those are even being gamed by people by studying leetcode. I’d be really curious what a high quality tech recruiter does vs the average.


  • We do require a BS in computer science

    The only scenarios where I’d think I wouldn’t require one are

    1. I want cheaper labor
    2. I am really desperate to fill a position
    3. The skills I need in a candidate are incredibly niche, thus I want to widen the applicant pool.

    #1 and #2 are indicative of other problems in your company. I get that you can be a good dev without a degree, but from an employer perspective, it seems like an easy way to save time and money on hiring. I am convinced that a lot of money is wasted on recruiters who throw everyone under the sun into the hiring process just so they can justify their existence.








  • Does it execute both, or does it execute the branch that is more likely to be valid? Branch prediction seems like it’d be way more performant than executing both branches until the result of the branch condition is available. If you think about it, what you’re proposing will cause the CPU to always execute instructions that are not meant to be executed when confronted with a branch whereas branch prediction will only execute these “useless” instructions in the unlikely scenario where the prediction is incorrect.
