Daily Coding Interview Question Newsletter

A daily newsletter delivering coding and interview questions from major tech companies with an integrated platform to run and test solutions. Target users are job seekers and engineers prepping for technical interviews.

The technical interview prep market is genuinely active right now, driven by ongoing waves of layoffs and rehiring cycles in tech that keep a steady stream of candidates in prep mode. LeetCode is the obvious incumbent here and has massive brand lock-in, with Neetcode, AlgoExpert, and a dozen newsletters already carving up the remaining attention — this space is crowded in a way that makes differentiation genuinely hard. The $2k–$10k/mo revenue band is realistic but likely represents a ceiling rather than a floor, since most users default to free tiers and churn the moment they land a job, making lifetime value structurally low. The single biggest risk is that there's no durable moat: the content is largely commoditized, the audience is transient by nature, and any growth in subscribers gets constantly eroded by people who prep, get hired, and disappear.
