Pre-Screening Interview Questions to Ask a Failure Analysis Engineer

Last updated on

Semiconductor fabs, medical device makers, automotive tier-one suppliers and contract manufacturers all hire failure analysis engineers. These questions surface the techniques they run at the bench, the failures they closed to confirmed root cause, and what to listen for in each answer.

TL;DR, what to screen for

The best pre-screening questions for a Failure Analysis Engineer test four things: the analytical techniques they personally run, failures they drove to confirmed root cause, how they reason when the sample is destroyed or there is only one return unit, and how they deliver a finding that implicates a colleague or a key supplier. Push past tool name-dropping: ask who loaded the sample, who ran the SEM, and who wrote the 8D.

  • Hands-on analytical technique
  • Root cause that shipped
  • Diagnosis under uncertainty
  • Delivering unwelcome findings

Why pre-screen failure analysis engineers before the lab tour and technical panel

Pre-screening failure analysis engineers saves your lab panel from candidates who have only read reports. Applicants come from fab yield teams, reliability groups, third-party test houses and quality engineering, and the resumes look identical: SEM, FIB, X-ray, 8D, FMEA. A resume cannot tell you whether they operated the tool or requested the scan, or whether their cases ended in a confirmed mechanism. Ten minutes of answers separates people who own a failure through to a corrective action from people who forwarded findings.

What actually matters when screening Failure Analysis Engineer candidates

  1. 01

    Technical depth

    Probe the analytical techniques they run themselves, from microscopy and cross-sectioning to electrical fault isolation.

  2. 02

    Work that shipped

    Look for failures they took to confirmed root cause, and what changed in the product afterwards.

  3. 03

    Diagnosis under uncertainty

    Test how they proceed when the sample is destroyed, the return is one unit, and everyone wants an answer today.

  4. 04

    Working across the org

    Check how they deliver a finding that blames a colleague's design or a major supplier.

Bench experience

4 questions
  1. 01How many years have you worked in failure analysis, and which industries have you done it in?

    Listen for

    Named industries (semiconductor, medical device, automotive, aerospace) with the failure types each brought: solder fatigue, ESD, corrosion, latent silicon defects.

    Generic engineering history with no distinct failure analysis role or case volume they can describe.

  2. 02Which analytical tools do you operate yourself for isolating the root cause of an electrical device failure?

    Listen for

    Specific tools they hands-on run: SEM, FIB, X-ray, scanning acoustic microscopy, curve tracer, OBIRCH or thermal emission, decapsulation and cross-sectioning.

    Lists tool names but cannot say whether they operated them or submitted samples to an outside lab.

  3. 03Walk me through the process you follow when a failed unit lands on your bench.

    Listen for

    Non-destructive steps first (documentation, X-ray, acoustic imaging, electrical characterisation) before any destructive decap or cross-section, with sample preservation called out.

    Jumps straight to cutting the part open, or describes a process with no evidence-preservation logic.

  4. 04What do you do to make sure the data you gather is accurate and the sample is not compromised?

    Listen for

    Chain of custody, ESD-safe handling, photographing at each stage, control units run in parallel, and recording the tool settings used.

    Treats accuracy as personal care rather than documented procedure and control comparison.

Confirmed root cause

4 questions
  1. 05Take a minute on camera to walk through one root cause analysis or FMEA you personally led, using a real example.

    Listen for

    A named failure mode, the analysis sequence, the physical evidence that confirmed it, and the FMEA line or design change that followed.

    Recites the eight disciplines or FMEA columns as theory with no case attached to them.

  2. 06Tell me about a failure analysis of yours that changed the product or process afterwards.

    Listen for

    A specific change that shipped: layout revision, underfill change, supplier process control, screening test added, with a before-and-after failure rate.

    Ends the story at the report with no evidence anyone acted on the finding.

  3. 07Describe a component failure you analysed where the findings were unexpected.

    Listen for

    A case where the first hypothesis was wrong, with the evidence that overturned it and how they re-ran the analysis.

    Only presents cases where the initial suspicion was confirmed, suggesting shallow or borrowed casework.

  4. 08Describe a time your failure analysis led to real cost savings.

    Listen for

    Scrap avoided, a recall narrowed, a supplier debit supported by their evidence, or a screening step removed once the mechanism was known.

    Claims large savings with no mechanism explaining how the finding produced them.

Diagnosis under pressure

3 questions
  1. 09Tell me about a failure you had to diagnose with only one return unit or a sample that was already destroyed.

    Listen for

    Sequencing decisions that preserve options, use of comparable units, reproduction attempts on good parts, and stating the confidence level honestly.

    Claims certainty from a single destroyed sample, or says the case was closed as no fault found and left there.

  2. 10How do you handle it when a significant product failure is escalating and everyone wants an answer the same day?

    Listen for

    Interim containment separated from root cause, staged updates to stakeholders, and refusal to publish a mechanism before evidence supports it.

    Offers a fast answer to relieve pressure, or describes freezing until the full analysis is complete with no containment.

  3. 11How do you deliver a finding when the root cause points at a colleague's design or a major supplier?

    Listen for

    Evidence-first framing, pre-briefing the owner before the wider meeting, and separating physical mechanism from blame in the report language.

    Describes conflict with design or sourcing teams, or softens conclusions to avoid the confrontation.

Credentials and logistics

1 question
  1. 12Which certifications, lab tool trainings or safety qualifications do you currently hold?

    Listen for

    Named credentials such as ASQ CRE or CQE, Six Sigma belts, IPC standards, plus chemical handling or laser safety training for decap and FIB work.

    Claims lab tool proficiency with no training record and no awareness of acid decap or chemical safety requirements.

How to score responses

Score every candidate on the same four criteria immediately after the screen. At this stage you are shortlisting for panel interviews, not making the final call.

  1. Technical depth

    35%

    5Runs their own analytical techniques and knows what each can and cannot resolve on a given failure.

  2. Work that shipped

    30%

    5Names failures driven to confirmed root cause, with the design or process change that followed.

  3. Diagnosis under uncertainty

    20%

    5Plans destructive analysis in the right order on a single sample, and states confidence honestly under pressure.

  4. Working across the org

    15%

    5Delivers uncomfortable findings with evidence that holds up, without softening the conclusion.

Failure analysis is explained at a screen: ask candidates to walk through an anonymised report on video and you hear whether they reason from image evidence or recite terminology.

Screening FAQ

Process basics

What should a failure analysis engineer screen cover before the technical panel?

Cover four areas: which analytical techniques they run themselves versus request from a lab, two or three failures they took to confirmed root cause, how they proceed with destructive-only samples or a single return unit, and how they communicate a finding that points at a design owner or supplier. That is roughly ten minutes of answers.

Do failure analysis engineers need certifications?

Certifications are useful signals, not requirements. Look for ASQ Certified Reliability Engineer or Certified Quality Engineer, Six Sigma Green or Black Belt, IPC-A-610 or J-STD-001 for electronics, and vendor training on SEM, FIB, acoustic microscopy or curve tracing. Hands-on case history matters more than any credential, so treat certificates as a tiebreaker.

Evaluating answers

How do you tell a real root cause from a plausible story?

A real root cause is reproduced or physically confirmed. Listen for evidence: a cross-section image showing the crack origin, a decap that exposed EOS damage, a failure reproduced on good units under the same stress, or a corrective action that dropped the field return rate. Vague phrases like "we suspected thermal stress" without confirmation are storytelling.

What are the biggest red flags in a failure analysis screen?

The strongest red flags are borrowed credit and destroyed evidence. Watch for candidates who cannot say who ran the tool, who jump to decap or cross-section before non-destructive imaging, who blame operator error without data, and who describe zero cases where their conclusion changed a design, process or supplier control.
