How We Vet Engineers: Technical Screening by Practising Engineers

How to vet embedded engineers: test the work, not the CV. Stalwart Innovations starts from a role brief, then practising engineers in the same discipline interview each candidate on scenario questions such as AUTOSAR configuration, UVM testbenches, DO-178C coverage or HIL debugging. A written assessment, reference checks and a screening summary follow before you interview.

Our technical screening process

01

1. Role brief

With your hiring manager we pin down the actual work, standards, tools, target hardware, seniority and the problems the engineer will face in the first months.

02

2. Targeted sourcing

We search for specific experience, such as an MCAL vendor, a DAL, a tester platform or a kernel subsystem, not keyword matches.

03

3. Recruiter pre-screen

Availability, notice period, location, compensation expectations and a check that the CV's projects hold up to basic questions.

04

4. Technical interview by a practising engineer

An engineer working in the same discipline interviews the candidate on design, debug and standards scenarios drawn from real work.

05

5. Written assessment

Where the role calls for it, a short written task: a code review, a configuration problem, a test design or a safety requirement to refine.

06

6. Reference and background checks

References from former leads on the work claimed, plus employment and education verification to the depth agreed with you.

07

7. Shortlist pack

You receive the CV, the screener's notes and assessment summary, then run your own interviews and make the decision.

Scenario questions by domain

Examples of the practical ground our screeners cover. Questions vary by role and seniority.

DomainWhat we probeExample scenario
AUTOSAR ClassicBSW and MCAL configuration, RTE, ComStack, OSA CAN signal reaches the bus but not the SWC: walk through the COM, PduR and RTE configuration you would check
Functional safety (ISO 26262)HARA, safety goals, ASIL decomposition, work productsDerive technical safety requirements for a given safety goal and explain the ASIL decomposition you would allow
Design verification (UVM)Testbench architecture, coverage closure, debugCoverage is stuck short of the goal on a FIFO: explain how you would find the holes and what you would change in the sequences
DO-178C softwareRequirements-based testing, structural coverage, DAL objectivesExplain what MC/DC coverage requires at DAL A, and how you would handle code that tests cannot reach
HIL testingRig configuration, I/O mapping, plant models, fault insertionA HIL test passes on one rig and fails on another: describe how you would isolate model, I/O and timing causes
Embedded Linux and firmwareBring-up, drivers, concurrency, memoryA board hangs during boot after a device-tree change: describe your debug sequence with a JTAG debugger and serial console
ATE test engineeringTest programs, pattern debug, correlationYield drops on one tester site only: explain how you would separate hardware, program and device causes

What you see before you interview

  • The candidate's CV, with the projects and standards the screener verified in conversation
  • Screener notes on strengths, gaps and the tools and platforms the candidate has used hands-on
  • A summary of the written assessment where one was set
  • Notice period, likely joining date, location preference and compensation expectations
  • Any ramp-up the screener expects on your specific toolchain, stated plainly

Why we screen this way

Standards-driven engineering roles are easy to misread from a CV. A candidate can list ISO 26262 or DO-178C without having produced a safety case or coverage evidence, or list AUTOSAR having only used generated configurations. Asking someone who does the work to probe the work is the most direct way to tell the difference.

The same screeners look at the roles we fill through staff augmentation, contract-to-hire, permanent recruitment and dedicated teams. Role-specific skills are listed on each role page, for example AUTOSAR engineers, VLSI engineers, avionics engineers and test engineers. Engineers looking for roles can start at careers.

Frequently asked questions

How do you vet AUTOSAR, ISO 26262 or DO-178C experience?

A practising engineer in the same discipline asks the candidate to work through scenarios: tracing a signal through COM, PduR and RTE configuration, deriving safety requirements from a safety goal, or explaining MC/DC objectives at DAL A. We also ask which work products the candidate owned and how they were reviewed or audited.

Who conducts the technical interviews?

Engineers who work in the same discipline as the role, for example an AUTOSAR integrator for BSW roles, a verification engineer for UVM roles or a test engineer for HIL roles. Recruiters handle availability and expectations; technical judgement comes from engineers.

Do candidates take a written test?

Where the role calls for it. Written tasks are short and practical, such as reviewing a code snippet against MISRA C, solving a configuration problem, designing test cases from a requirement or refining a safety requirement. We do not use generic aptitude tests.

Can we add our own technical rounds?

Yes, and most teams do. Our screening is designed to save your engineers time on unsuitable candidates, not to replace your interviews. You can also share your own questions or a take-home task for us to include at screening stage.

Which tools should our engineers know, and do you check them?

It depends on the role: Vector DaVinci and CANoe for AUTOSAR, dSPACE or NI for HIL, Lauterbach TRACE32 for embedded debug, Synopsys, Cadence or Siemens simulators for verification, Advantest V93000 or Teradyne UltraFLEX for ATE. We confirm hands-on use in the interview and flag where ramp-up on your tools applies.

Do you run reference and background checks?

Yes. We take references from former leads on the work the candidate claims, and verify employment and education history to the depth you need. Additional checks your security policy requires are agreed with you before the search starts.
