CS Foundations & Interview PrepIntermediate8 modules~4.0 hours hands-on
The Coding Interview Loop
Practice the complete coding-interview workflow: clarify the problem, establish contracts, derive and improve a solution aloud, test it deliberately, and perform realistic timed mocks.
// What you'll be able to do- Understand the signals interviewers evaluate
- Turn ambiguity into examples, constraints, and invariants
- Produce a correct baseline and improve it transparently
- Narrate decisions without drowning the signal
