On Coding Interviews: What Works, What Doesn’t, and Why It Matters

The relationship between technical interviews and real-world performance remains one of the most debated topics in software engineering recruitment. While you may be reading this because of a recent interview experience we shared, this post aims to explore a broader and more important question: how can companies better identify talented developers? Although many organizations have established interview processes they consider sufficient, the challenge of false negatives – rejecting qualified candidates – continues to impact both companies and developers [^googlehomebrew]. As Joel Spolsky notes, "A lot of good programmers end up getting rejected — while, even worse, companies end up hiring people who are good at passing tests, but under-perform in the real world" [^joelrecruiting]. Drawing from industry anecdotes [^seniorinterviews], professional discussions [^hackernews], and academic research [^devstalk], this pos

Purpose

Bootstrap knowledge of LLMs ASAP. With a bias/focus to GPT.

Avoid being a link dump. Try to provide only valuable well tuned information.

Prelude

Neural network links before starting with transformers.

Configure prettier, eslint, husky (pre commit hook), lint-staged in react + typescript project

Steps to configure prettier, eslint, husky (pre commit hook), lint-staged in react + typescript project created using create-react-app. This is opinionated configuration with airbnb's style guide as the base style guide.

Step 1 :: Setup prettier

1.1) Install prettier as dev dependency.

npm install --save-dev --save-exact prettier

Node.js on Apple Silicon

Node Version Manager (https://github.com/nvm-sh/nvm) works perfectly across native node installations as well as emulated Rosetta installations. The trick I am using here is to install one LTS version of node under Rosetta and another stable version as native binary.

TODO

find a way how to run the same node version on both platforms

These instructions will explain how to install tensorflow on mac with cuda enabled GPU suport. I assume you know what tensorflow is and why you would want to have a deep learning framework running on your computer.

Prerequisites

Make sure to update your homebrew formulas
