Let's begin — how would you model this order-pricing system?

Build → Design → Curveball

STEP 01

Meet your AI interviewer

Pick a round — DSA, Machine coding, LLD or System design. A voice AI sets the problem in a real coding room.

AI voice interviewerReal coding room

STEP 02

Build it, out loud

Write a working solution while the AI listens, then probes your choices live.

Live voiceDesign probes

STEP 03

Handle the curveball

The AI adds a half-baked feature and watches you extend it. Hidden tests decide correctness — never the model.

Adaptive follow-upsHidden-test execution

STEP 04

Get the report + verdict

Minutes later: a report quoting your code, scored on the rubric, signed by a senior engineer.

The report is the product

A report card that quotes your own code.

Not a vibe score. Every number traces to the round — real-execution correctness, rubric design, signed verdict.

SOLID: single responsibility Writing testable units Concurrency & locks

What's working

Clean strategy split in PricingEngine.apply() — new rules drop in without touching the core.

All 9 hidden tests pass, including the concurrency curveball.

Where you lost points

processOrder() does three things — split it for testability.

Sparse tests: only the happy path is covered.

Watch your readiness climb into Strong Hire.

Every mock scores your readiness against the hire bands. Real progress isn't a straight line — it dips and climbs, until you're firmly in Strong Hire.

The interview rounds

One AI. Every round you'll actually face.

Each round runs a frozen rubric — so your report means the same thing to every recruiter.
