Welcome to the NUPOC Interview Portal

Five tiers. Work through them in order:

• Basic — sanity checks on the fundamentals.
• Intermediate — standard interview material.
• Difficult — stretch problems.
• Capstone — multi-part, 15 minutes, gated. Solve these unassisted and you're interview-ready.
• Naval Reactor — post-capstone bonus. Submarine-specific. Optional stretch.

Tip: if you can borrow an iPad or drawing tablet, do. Hand-drawing is far more natural than a mouse for these problems.
