Scope#

Build and practice system designs for Hydrocrate interviews while keeping session notes, design attempts, critique, and polished reference material distinguishable.

This collection belongs to the main notes repository but remains separate from System design. Do not copy, merge, or cross-link material between the two collections unless Raj asks for it. Record possible overlaps for deliberate consolidation later.

Current state#

The collection intentionally starts with minimal structure. Use the Codex session prompt to start a new chat, then copy the practice session template for each interview exercise.

Notes

  1. Codex session prompt Start a separate Codex chat that maintains this interview guide without changing the older system-design collection.
  2. Practice session template Capture one interview attempt, its critique, and the next practice target without erasing the original reasoning.
