Coding Round 1 utilized a progressive multi-part format requiring a working solution at each stage before proceeding.

Coding Round 2 focused on systems-flavored problems, specifically state management, concurrency, and memory efficiency.

Prioritize getting a correct, working solution early in multi-part coding rounds before attempting to iterate or optimize.
Be prepared to defend every architectural decision made in take-home projects with specific reasoning.
In system design, focus on the specific constraints provided (e.g., GPU allocation) rather than generic high-level designs.
