Synthesis interviews probe judgment with numbers across six themes. Each lesson below pairs every question with a precise answer, a follow-up probe, and the common wrong answer.

Flow of the six interview themes.

Six themes in teaching order, from inference to handoff.

Lesson	What it covers
Flow and Inference	Elaboration, resource inference, and latch traps.
Optimization and Mapping	Boolean effort, mapping, and worked area and depth numbers.
Timing and Constraints	Hand-derived slack, constraint intent, and a runnable checker.
Sequential and Datapath	Flops, FSM inference, sharing, and pipelining numbers.
Power and Test	Dynamic power arithmetic, clock gating, and scan insertion.
Verification and ECO	Equivalence checking, ECO judgment, and handoff checks.

Check yourself What separates a strong answer from a weak one on a slack question?

Arithmetic: the strong answer derives the number from period, delays, and uncertainty. The weak answer names the concept without computing.
