Rabbit Hole - Data Science Case Prep

What it does

Rabbit Hole is a case study interview practice platform for data scientists. Practice with real cases from FAANG companies — complete with production-scale datasets, a built-in SQL editor, and detailed AI-powered feedback on your analytical thinking. Most candidates prep coding and stats but walk into the case study round cold. Rabbit Hole lets you practice the way you'll actually be tested.

Real interview cases tuned by the interviewers who actually run them. Pick a case, run a multi-stage mock, and leave with a debrief tied to your transcript.

More than 50 real cases from FAANG interview loops. Real interviews are verbal. You practice the same way — out loud, with live pushback. A live conversation on a real case. The follow-ups, the redirects, the curveballs — calibrated by people who run this round at the actual company. “Two things changed in the last month. Could they be interacting?” What was strong, what was weak, and what would’ve cost you the round — with the fix. Your one soft spot is segmentation. You reasoned well in aggregate but didn’t split the problem — break it out by user type and network size (new users vs. power users with large networks) before drawing conclusions.

  I Built a Site That Curates Weird YouTube Rabbit Holes Daily2025 · yourabbit.com · ▲59

  I built Yourabbit.com — a site that curates hand-picked YouTube rabbit holes grouped by themes like quirky psychology, obscure tech, weird facts, and binge-worthy oddities. It’s not driven by the YouTube algorithm — every collection is themed and curated manually (for now), with a backend I’m automating to fetch and organize new rabbit holes daily. Built as a hybrid Astro + Next.js project, optimized for static generation and speed. I’m also pairing videos with custom summaries and commentary (using AI), and would love feedback from the HN crowd on: Content model (too wide? not specific…
