Design Verification · Interview Questions
Interview process
A DV loop opens with a resume-led hiring-manager round, then four technical rounds that weight live coding, UVM methodology, project depth, and behavioral signal. Coding and methodology carry the most weight (~60% combined), so a clean SystemVerilog/UVM coding pad and story-ready projects both matter.
The rounds, in order
5 rounds- 1
Hiring manager round
45–60 min · hiring managerResume-led screen that also samples coding and behavioral signal
What they ask- Walk through your resume, then go deep on one project (~70–80% of the round)
- Your specific role and responsibilities versus the team's
- A short Verilog/SystemVerilog coding question (~10%)
- One or two behavioral prompts — ownership, conflict, deadlines (~10%)
- 2
Coding round
45–60 min · video + coding pad≈30% weightLive SystemVerilog/Verilog and language depth
What they ask- Write clean SystemVerilog on a shared pad — classes, queues, constraints
- rand vs randc, constraint solve order, and fork/join variants
- OOP: inheritance, polymorphism, virtual methods, deep vs shallow copy
- A small algorithmic problem (arrays/strings) in SV or C
- 3
Coding + methodology round
60 min · onsite panel + coding≈30% weightUVM testbench architecture on top of live coding
What they ask- Build a UVM env for a given DUT — agent, sequencer, driver, monitor, scoreboard
- Coverage model and a concrete closure plan (bins, crosses)
- Scoreboard / reference-model and end-to-end data checking
- Write an SVA property and debug a failing seed from a waveform
- 4
Resume-based round
45–60 min · onsite panel≈20% weightDeep dive on your projects and real contributions
What they ask- End-to-end walkthrough of a project you owned
- Your verification plan — features, stimulus, checks, and coverage you drove
- The hardest bug you root-caused, from symptom to fix
- Trade-offs and decisions you personally made
- 5
Behavioral round
45 min · hiring manager / peer panel≈20% weightOwnership, collaboration, and closure under pressure
What they ask- A time you protected quality under a slipping schedule
- A disagreement with a designer or lead and how you resolved it
- A failure or escaped bug and what you changed afterward
- Thoughtful questions for the team
How to prepare
- Resume stories: rehearse each project end to end and lead with your own role and responsibilities, not the team's.
- Coding: drill SystemVerilog on a shared pad — constraints (rand/randc, solve-before), OOP, queues and arrays — plus one C/algorithm warm-up.
- Methodology: be able to whiteboard a full UVM environment (agent, sequencer, driver, monitor, scoreboard) and defend your coverage-closure plan.
- Debug: prepare a real story — symptom → hypothesis → waveform evidence → root cause → fix — and be ready to write an SVA property live.
- Behavioral: have two or three STAR stories on ownership, conflict, and a deadline where you protected quality.
