For semiconductor and chip-design teams

Assess chip‑design skill, not keyword matches

Test RTL design, verification, physical design and embedded firmware with questions built for hardware: circuit and block diagrams, written design reasoning, and code.

The problem

Why generic tests fail chip-design hiring

  1. 01

    Generic coding tests miss hardware skill

    An algorithm puzzle says little about whether someone can write clean RTL, build a UVM testbench or close timing. Hardware roles need hardware questions.

  2. 02

    A small pool makes every wrong rejection expensive

    There are only so many verification or physical-design engineers on the market. A screen that rejects a good engineer on a technicality costs you weeks.

  3. 03

    Senior engineers spend their time on first rounds

    Your design leads are the only people who can judge the answers, so they end up interviewing candidates who should have been filtered out earlier.

  4. 04

    Remote tests invite outside help

    Design questions with well-known answers are easy to look up or pass to a friend. You need to know the candidate worked alone.

How it runs

From an open req to a shortlist

  1. 1

    Build the test by domain

    Combine multiple-choice fundamentals, diagram questions, written design questions and coding. Generate a first draft from the job description, then have your engineers review it.

  2. 2

    Let candidates draw and explain

    Diagram questions give candidates an editor to draw circuits, block diagrams and state machines. Subjective questions ask them to explain a design decision in their own words.

  3. 3

    Proctor the session

    TriNetra records the webcam, the screen and a phone camera on the desk. The CheqMate AI integrity agent can lock the computer into the test window.

  4. 4

    Review scored answers, not raw scripts

    Written answers are AI-evaluated against VLSI-specific categories. Your engineers see the score, the reasoning and the answer side by side, and can override any score.

FAQ

Common questions

Which hardware domains can we test?

TalentDecrypt is built for RTL design, design verification, physical design, DFT, analog design and embedded firmware. Write questions in your own domain, and written answers are marked against VLSI categories rather than generic ones.

Can candidates write and simulate HDL code?

The coding editor runs general-purpose languages such as C, C++, Python and Java, which suits embedded C, firmware and scripting questions. HDL and design knowledge is tested with diagram, written and multiple-choice questions. Your engineers review the written answers beside the AI score.

How do we stop a good engineer being rejected by the AI score?

The AI marks first and shows its reasoning beside the answer. Your engineer can change any score, and theirs is the one that stands.

Does it work for campus hiring as well as lateral?

Yes. The same platform runs a large campus batch with a live proctoring wall, and a single senior candidate with a harder, longer test.
