Nordic Semiconductor Interview & Assessment Preparation

Technical Assignments, Skill & Ability Tests, Multi-Round Interviews

Guide country context: Norway · Industrial Technology

Hiring processes can vary by country, role, business unit, and year.

Nordic Semiconductor is one of the few Norwegian companies that publishes its recruitment process in detail, which makes preparing for it unusually tractable. The published sequence is: application through their recruitment system with CV, motivational letter and transcripts; a first interview; assessments if that goes well — technical assignments, skill tests, ability tests or personality tests, with feedback given in the following interview; further interviews depending on the position and level; a consent-based background check; then an offer conversation with the hiring manager. Nordic describes a flat organisation with straightforward decision-making, and the interviews reflect that.

ℹ️ This preparation guide is independent and is not official Nordic Semiconductor material. It summarises publicly available candidate guidance from nordicsemi.com and helps you practise similar skills and interview formats. The number and type of stages depend on the position, field of expertise and seniority. Always follow the instructions in your own invitation email.
⚠️ Nordic Semiconductor publishes its recruitment process and describes it as mutual — both sides selecting each other. It states that assessments are used after a successful first interview and that you receive feedback on them in the next interview. Take that at face value: this is a process where asking substantive questions is expected rather than tolerated.

📋 Hiring Process

  • 1
    Application through the recruitment system official
    Nordic states that applications go through their recruitment system, that returning applicants can reuse an existing profile, and that new applicants create one and upload a CV, a motivational letter and educational transcripts. Transcripts being requested up front is worth noting — academic record carries weight on early-career routes.
    → Write a genuine motivational letter naming the product area; transcripts are expected, so have them ready as PDFs
  • 2
    First interview official
    The opening conversation, framed by Nordic as mutual — for them to get to know you and for you to get to know them. Expect your background, your motivation for embedded and wireless work, and what you are looking for.
    → Prepare real questions about the team and the products; the process is explicitly two-directional
  • 3
    Assessments official
    Nordic states that if the first interview goes well you may be asked to complete assessments: technical assignments, skill tests, ability tests or personality tests, with feedback provided in the upcoming interview. Which ones you get depends on the role.
    → Ask which assessments you will get — Nordic already tells candidates the categories, so it is a fair question
  • 4
    Further interviews official
    Nordic states that the number of interviews depends on the position, field of expertise and level. Senior and specialist roles run more rounds. Later rounds typically include the technical team and go deep.
    → Expect your assessment results to be discussed — prepare to talk about them without defensiveness
  • 5
    Background check official
    Nordic states that your consent is requested for a background check and that the process does not begin without your approval. This is standard Norwegian practice and is run late, on the preferred candidate.
    → Have referee details ready; a check at this stage is a positive signal, not a hurdle
  • 6
    Job offer official
    Nordic states that the hiring manager approaches you to clarify expectations and either offers the position or gives feedback, and that they explain the benefits of employment. Nordic also states that salaries are fair and competitive and adjusted to local market expectations.
    → Use this conversation to settle expectations properly — Nordic frames it as a clarification conversation, so treat it as one

📝 Assessments

Technical Assignment case technical

Nordic states that assessments after a successful first interview may include technical assignments. For engineering roles this is typically a piece of realistic work in your domain — an embedded exercise, a design problem, a debugging scenario — with the reasoning discussed afterwards rather than the artefact scored in isolation.

Measures: Applied technical judgement, constraint awareness, debugging method, clarity of explanation

  • Document your reasoning as you go; Nordic gives feedback on assessments in the next interview, so the discussion is where the marks really land
  • For embedded work, address memory, power and timing explicitly — these are the constraints the company lives inside
  • Show your debugging method, not just the fix; how you narrowed it down is the transferable signal
  • State what you did not have time to do and what you would do next

Common mistakes

  • Submitting a working answer with no explanation of the trade-offs
  • Ignoring resource constraints because the exercise ran on a desktop
  • Hiding the parts you were unsure about instead of flagging them
  • Over-scoping and delivering something unfinished with no note about it
  • Being unable to re-derive your own solution in the follow-up conversation
Skill Test technical knowledge

Nordic lists skill tests among the assessments it may use. These target fundamentals in the role's domain — C and embedded concepts, digital or analog design basics, protocol knowledge — rather than general reasoning.

Measures: Domain fundamentals, accuracy, breadth within the specialism

  • Revise fundamentals rather than exotica: pointers, memory layout, concurrency, interrupts, fixed-point arithmetic
  • Refresh the protocol basics relevant to the role — Bluetooth Low Energy concepts, low-power operation, radio basics
  • Do not guess wildly on knowledge items; a clean blank is usually better than a confident error you then have to defend
  • Review your own CV technologies — the test tends to follow what you claimed

Common mistakes

  • Preparing algorithm puzzles instead of embedded fundamentals
  • Neglecting the low-power and radio side of the domain
  • Being caught out on something listed on your own CV
  • Rushing and misreading the constraint in the question
Ability Test & Personality Test cognitive assessment

Nordic lists ability tests and personality tests among the possible assessments, and states that you receive feedback on them in the next interview. The ability test is typically short and strictly timed; the personality questionnaire is untimed and describes how you prefer to work.

Measures: Abstract and logical reasoning under time pressure; working style, collaboration preferences and resilience

  • Practise matrix and figure-series abstract reasoning specifically — it is the most common format and the least practised
  • Budget your time per item and move on; these tests are usually built so nobody finishes
  • Answer the personality questionnaire consistently and honestly, because it will be discussed with you directly afterwards
  • Prepare to talk about your own results without defending them — Nordic frames the feedback as a conversation

Common mistakes

  • Only practising numerical reasoning
  • Trying to present an idealised profile that the next interview then contradicts
  • Getting stuck on a single hard item
  • Treating the feedback conversation as a challenge rather than a discussion
  • Taking the tests on a phone or between other commitments

🎤 Interviews

First Interview

Nordic frames the whole process as mutual selection, and this round is where that is most literal. Your background and motivation are explored, and you are expected to interrogate the role in return.

Format: Conversation with the recruiter and often the hiring manager, typically 45 minutes

What interviewers look for

  • Genuine interest in wireless, embedded and low-power engineering
  • Understanding of what Nordic actually makes and who buys it
  • Ability to explain your own work clearly
  • Fit with a flat organisation and mutual trust
  • Realistic expectations about location and role

Focus areas to practise

  • Why embedded and wireless rather than general software
  • A project you built end to end, including the failures
  • What you know about Nordic's product families and their customers
  • How you learn a new platform or SDK
  • What you want from your next role
  • Have built something, even small, with a Nordic dev kit or comparable hardware, and be able to talk about what surprised you
  • Prepare three real questions — Nordic explicitly frames the process as both sides selecting, and empty questions waste the opening
  • Explain your motivational letter's claims in person; they will be picked up
  • Be clear about Trondheim, Oslo or wherever the role sits, and about relocation
Technical Interview with the Team

Nordic states the number of interviews depends on position, expertise and level. For engineering roles the later rounds go deep with the people you would work with, and your assessment results are typically discussed here with feedback.

Format: Deep technical discussion with engineers, 45–90 minutes, sometimes across more than one round

What interviewers look for

  • Real depth in your own claimed domain
  • Constraint-aware thinking — memory, power, timing, cost, yield
  • Systematic debugging rather than trial and error
  • Honesty about the limits of your experience
  • Ability to receive feedback on the assessments without defensiveness

Focus areas to practise

  • Debugging an intermittent fault with limited visibility
  • Trading power against latency or throughput
  • Working within tight memory or silicon-area constraints
  • A design decision you would now make differently
  • How you validate that something actually works
  • Know your own thesis, project or design well enough to defend the measurements and the choices
  • Narrate your reasoning out loud; silence is unscoreable in a technical discussion
  • When you hit the edge of your knowledge, say so and describe how you would find out
  • Ask what the team's hardest current problem is — it is a real question here and the answer tells you a lot

🧭 How this differs by role

The process is not the same for every role. Find the closest match to the job you applied for — the assessments and interviews below are the ones reported for that role family.

Embedded software & firmware

Assessments

  • Technical assignment or take-home
  • Skill test on C and embedded fundamentals
  • Possible ability test

Interviews

  • First interview
  • Technical interview with the engineering team
  • Manager interview

This is the heart of the company: nRF SoCs, Bluetooth Low Energy, Thread, Matter, Zephyr, the nRF Connect SDK. Be ready to discuss memory constraints, power budgets, interrupt handling and debugging without a debugger. Having actually flashed a dev kit and built something is worth more than any certificate.

RF, analog & IC design

Assessments

  • Technical assignment in your design domain
  • Skill test on fundamentals
  • Design discussion

Interviews

  • First interview
  • Deep technical interview with design engineers
  • Manager interview

Expect genuine depth on your thesis or design work — Nordic hires RFIC and analog designers straight from strong master's and PhD programmes, and the technical interview goes as deep as your own work allows. Know your own results well enough to defend the measurements.

Students, interns & graduates

Assessments

  • Technical assignment
  • Ability test
  • Personality test

Interviews

  • First interview
  • Technical interview
  • Team interview

Transcripts are part of the application, so grades matter more here than on an experienced-hire route. Summer internships (including in Sweden) are advertised through Nordic's careers system and recruited well ahead of the summer — apply in the autumn or winter.

Software tools, cloud & applications engineering

Assessments

  • Coding exercise or take-home
  • Skill test
  • Customer-scenario discussion for applications roles

Interviews

  • First interview
  • Technical interview
  • Cross-functional interview

Applications engineering is customer-facing: you help other companies' engineers ship products on Nordic silicon. Prepare to explain a hard technical constraint patiently to someone who is frustrated and under their own deadline.

Quality, supply chain & commercial

Assessments

  • Case or analytical exercise
  • Ability and personality assessment

Interviews

  • First interview
  • Functional interview
  • Manager interview

Semiconductor supply chains are long, capital-intensive and volatile. Evidence of handling constrained allocation, forecasting error or supplier escalation is directly relevant and rare in candidates.

🏛️ Values & Framework

How Nordic Semiconductor works and hires

Nordic describes an agile organisational culture with straightforward decision-making, enabled by a flat organisation and mutual trust, and states that salaries are fair and competitive and adjusted to local market expectations. It presents recruitment as a two-way selection in which both parties choose. For candidates the practical consequences are: expect autonomy rather than direction, expect to be asked what you want as well as what you can do, and expect honesty to be rewarded more than polish.

Flat organisation and mutual trust Straightforward decision-making Technical depth and curiosity Mutual selection — both sides choosing Autonomy with accountability Innovation in low-power wireless
  • Trust: describe being given latitude and what you did with it
  • Straightforward decisions: describe cutting through a stalled discussion with a clear recommendation
  • Depth: pick one project and be able to go four questions deep on it
  • Mutual selection: bring real questions and real criteria of your own
  • Autonomy: describe owning an outcome without supervision
  • Curiosity: describe something you learned recently because you wanted to, not because you had to

⏱️ Preparation Plans

  • Re-read Nordic's published recruitment process so you know exactly which of the six stages you are at
  • Prepare your strongest project to four questions of depth, including what failed
  • Have CV, motivational letter and transcripts ready as clean PDFs
  • Run one timed abstract-reasoning set
  • Write three genuine questions about the team and the product — the process is explicitly mutual
  • Daily timed abstract and logical reasoning
  • Revise embedded or design fundamentals for your specialism rather than algorithm puzzles
  • Refresh Bluetooth Low Energy and low-power concepts if the role is wireless
  • Prepare five STAR stories including a debugging story and a failure
  • Practise narrating a debugging process out loud, step by step
  • Daily reasoning practice plus one domain-fundamentals session
  • Complete one realistic technical assignment and write the reasoning document that goes with it
  • Build a story bank of seven examples covering autonomy, debugging, collaboration, learning and failure
  • Build something small on a dev kit if you have one, so you have a first-hand story
  • Research Nordic's product families, key markets and recent announcements
  • Run a mock technical interview where the interviewer keeps probing deeper
  • Consistent timed accuracy on abstract, inductive and logical reasoning
  • Two full mock technical interviews with an engineer who will push into the gaps

  • Story bank of ten, rehearsed aloud, honest about limits
  • Prepare for the assessment-feedback conversation: how you would respond to an unflattering result
  • Line up referees ahead of the consent-based background check
  • Prepare the offer conversation: salary in NOK, relocation, and what 'fair and competitive, adjusted to local market' means for your city

❓ Frequently Asked Questions

What is the Nordic Semiconductor recruitment process?
Nordic publishes it. The stages are: application through their recruitment system with CV, motivational letter and educational transcripts; a first interview; assessments if that goes well — which may include technical assignments, skill tests, ability tests or personality tests, with feedback given in the next interview; further interviews, the number depending on position, field of expertise and level; a background check that requires your consent; and a job offer conversation with the hiring manager, who clarifies expectations and explains the benefits.
What assessments does Nordic Semiconductor use?
Nordic states that assessments may include technical assignments, skill tests, ability tests and personality tests, and that they come after a successful first interview. It does not name a provider, so prepare formats rather than brands: a realistic technical task in your domain, fundamentals in your specialism, timed abstract reasoning, and an untimed work-personality questionnaire. Nordic also states you get feedback on them in the following interview.
Do I need to send transcripts?
Nordic's published process asks for a CV, a motivational letter and educational transcripts at application. That is worth taking seriously: academic record is being looked at, particularly on student, intern and graduate routes. Have clean PDFs ready rather than scrambling for them mid-application.
How many interviews will I have?
Nordic says the number depends on the position, the field of expertise and the level of the position. Early-career roles tend to run fewer rounds; senior, specialist and design roles run more, and typically go deeper technically each time. Ask the recruiter after the first interview — this is a company that publishes its process, so it is not a coy question.
What technical depth should I expect?
Real depth in whatever you claimed. For embedded and firmware roles expect memory, power, timing, interrupts and debugging with limited visibility. For RF, analog and IC design expect your thesis or design work to be explored until you reach the edge of it — which is normal and is not a failure. Constraint-aware thinking matters more than algorithmic cleverness here.
Do I need to speak Norwegian?
For most engineering roles, no. Nordic is an international company with a large non-Norwegian workforce and English is the working language across much of engineering. Some commercial, administrative and local roles will want Norwegian. Ask on the first call, and note that Norwegian is genuinely useful for life outside work even where the job does not require it.
What is the background check and should I be worried about it?
Nordic states that your consent is requested and the process does not begin without your approval. In Norwegian practice this is run late, on the preferred candidate, and typically covers identity, qualifications and references. Reaching this stage is a positive signal. Line up referees who have seen your recent work and tell them what the role is.
When do internships and graduate roles open?
Summer internships and graduate positions are advertised through Nordic's careers system and, like most Nordic-region employers, are recruited well ahead of the summer — commonly in the autumn and winter beforehand. Set up alerts rather than checking in spring, by which point most positions have gone.
