1. Dates, deadline and procedures

When does the TNO Trainee Programme start?

The next TNO Trainee Programme will start in September 2022. The application deadline is closed. The first TNO Trainee Program of 2023 will start in February 2023.

When is the deadline for applying?

The application procedure for the February 2023 trainee programme will start in September 2022. The exact date will be announced later in the year.

In what language should I write my application (CV, motivation letter)?


Can I access my supporting document and/or video after I have submitted it?

You can no longer access the originally uploaded versions. In case you accidentally uploaded a wrong version of your documents, you can send the right version to [email protected].

Are all documents really necessary?

Yes. We will not consider your application if any of these files are missing:

  • Resume
  • Motivational letter
  • Video

When do I know if I am through to the online assessment?

The first announcement will be on 3 May. We will then let you know whether or not you are invited to the next step; our online assessment. The outcome of that assessment together with your application will lead to either an invite for the trainee selection day or a rejection. You will be notified about that 24 May at the latest.

What can I expect when I am through to the next round; the online assessment?

Our partner LTP provides you with an online assessment that consists of questionnaires about your personality, drives, values and capabilities. If the results of your tests, cv, motivation and video pitch match our wishes and criteria for the TNO Trainee Programme, we will invite you to the trainee selection day.

What does the trainee selection day consist of?

During the selection day (3 June 2022), you will have two job interviews, fulfill a group assignment and give a short pitch. You will also get to know current and former trainees.

The trainee selection day will take place in The Hague, Anna van Buerenplein 1.

A few days before the trainee selection day you will receive your personal planning for the day.

What are the important dates in the selection process for September 2022?

Deadline for applying: 1 May
Trainee selection day: 3 June
Final interview: 9, 13 & 14 June
Presentation of the terms of employment: 20 June
Start: 1 September

I cannot attend the trainee selection day, can I still apply for the TNO Trainee Programme?

The purpose of the trainee selection day is for us to meet you and for you to meet TNO. Therefore we find it important that you attend this day. If you cannot attend the trainee selection day, please inform us as soon as possible.

How do the guidelines around COVID-19 influence the trainee selection?

With COVID-19 still among us, we are of course monitoring official guidelines closely. We keep a close eye on  RIVM guidelines. These guidelines are leading for the organisation of the trainee selection and the trainee selection day. We will make sure everyone can comply with these guidelines. 

Can I withdraw my application?

Yes, you can. Depending on what stage you are in the process, please contact the recruiter or mail [email protected].

I have not been shortlisted or selected. Will I be able to ask why my application has not been accepted?

We do our utmost to be as transparent as possible about our process and the qualifications we select upon. Due to the huge amount of interest for the TNO Trainee Programme, we unfortunately cannot give feedback on a personal note after round 1 (cv assessment) and 2 (online assessment). After joining us at the Trainee Selection Day or the final interviews, we will of course inform you personally.

What kind of screening is involved?

All trainees need a certificate of conduct and additionally a screening by the General Intelligence and Security Service.

When is the next TNO Trainee Programme opening up?

In September 2022 we will be opening up the procedure for the TNO Trainee Programme that starts February 2023.

2. Video

What is it you are looking for in my video?

We want you to tell us what makes you tick, and that can be anything. Maybe you are into a Michael Reeves way of experimenting, or maybe your biggest dream is to develop an awesome roller coaster. We are looking for something extra.

What language do I use in my video?

Please record your video in English.

How long does the video need to be?

The length is less important than the size of the video. But a maximum of 5 MB means it will be a short video (30 seconds or less). There are several online tools available to compress your video when needed.

How professional does my video need to be?

We all understand some of you may be more natural or more at ease in front of a camera. We also understand if English is not your mother tongue. Do not worry about that. Be yourself.

What kind of video format are you supporting?

Our applicant tracking system supports MP4, MOV, WMV, MPG and MPEG formats. Be aware that a video in any other format cannot be uploaded.

Help! I just can’t upload my video

If size and format are not the issues with an uploading problem, please send an e-mail to [email protected].

3. The TNO Trainee Programme

How many trainee spots are available?

We have a maximum of seven spots available.

Do I have influence on what my first assignment will be?

That depends. When more than one research manager is interested in your profile, your preference will of course be taken into account. In any case we will do our best to find the best first spot for you.

What are the regular working hours?

The TNO Trainee Programme is a fulltime programme. Meaning: Monday till Friday, 40 hours a week. Our offices open during regular business hours.

Where will I be working?

That depends on the unit you will be working for, but it will be one of our Dutch locations. Our head office is based in The Hague. See all our locations.

Is there a dress code at TNO?

No, there isn’t. Check our socials if you want to see what our colleagues look like. For the selection day, we advise business casual.

Will I receive a certificate or reference letter at the end of the TNO Trainee Programme?

No, you will not. The TNO Trainee Programme means you get to work in different roles, which you can put on your resume. 

Is there any way to extend my TNO Trainee Programme?

No. The TNO Trainee Programme ends after two years. We do hope, of course, that you will continue working at TNO.

What is the difference between a junior scientist or a TNO trainee?

When you have the ambition to go in deep into a certain area of expertise as a scientist and want to develop professionally in that role, a starter position as a junior scientist instead of that as a trainee, sounds as a better fit. As a junior scientist you automatically enroll in our Talent Development Programme.

4. International applicants

Does TNO provide accommodation during the selection process if I need to be present in person?

When needed, we reimburse hotel costs. Please check with HR first before booking [email protected].

What services do you offer for impats?

TNO takes care of a number of things for new employees from abroad. Ranging from accommodation to tax and language help.

Do I need to live in the Netherlands to qualify for a trainee position?

Please note we only consider applications from Europe based residents. If you live in the Netherlands or another European country but you are a non-EU citizen, TNO can provide sponsorship for your residence permit in the Netherlands.

Do I need to speak Dutch to be eligible to apply?

In general, TNO is a Dutch organisation. Most people within TNO are able and willing to speak English and important formal internal policies are also published in English. Some units though have predominantly Dutch speaking clients, and therefore speaking Dutch can be a requirement. Once you start the TNO Trainee Programme, we do offer Dutch courses.

How do I qualify from abroad?

The same as any other applicant. Check our selection criteria and keep in mind that due to your country of origin screening processes may take longer and we only reimburse relocation costs for European citizens coming to the Netherlands.

5. Study background and qualifications

What are the selection criteria?

  • You received your Master’s degree no longer than two years ago, counting from 1 September 2022, the starting date of the programme.
  • You have a bachelor's degree in a STEM discipline (Science, Technology, Engineering or Mathematics). In particular, we are looking for: physics, electrical engineering, computer science, aerospace engineering, mechanical engineering and (applied) mathematics.
  • You have a master's degree in:
    • a field of study that shows breadth and connection. For example, a Master's degree in Industrial Engineering & Management, Innovation Management, Transition Management or Industrial Design. Or:
    • a Master's degree in a technical study, but you know and can demonstrate that you want to connect with other disciplines.
    • You have a broad interest, which is demonstrated by your combination of Master's and Bachelor's degrees, and/or the extra curricular activities you have undertaken in addition to your studies.
    • You live within Europe.

    In your motivation letter and video we hope to see that:

  • You have an extensive knowledge base and experience to help solve societal and economic issues.
  • You are driven by knowledge and like to translate it into practice.
  • You want to innovate and look beyond the status quo.
  • You are bold in generating new ideas.
  • You have strong communication skills, which allow you to connect with the people around you and work towards new solutions.
  • You want to excel, you love a challenge and are comfortable with taking responsibility.
  • You take control in your work as well as in your own development.
  • You have a broad interest, which is shown by extracurricular activities in addition to your studies

Is it important to have extracurricular activities on your resume?

Within TNO we value professional skills as well as (inter)personal skills. These skills can be developed within or outside your study or work. We look at the experiences you gathered, what you learnt from them and how the result of that learning process is visible in other experiences.

What level of studies is required?


I will receive my master’s degree after the start date of the TNO Trainee Programme. Can I still apply?

No, you need to have your diploma by the day you start, 1 September 2022.

Which study backgrounds are you looking for?

Ideally you have a bachelor's degree in a STEM discipline (Science, Technology, Engineering or Mathematics). In particular, we are looking for: physics, electrical engineering, computer science, aerospace engineering, mechanical engineering and (applied) mathematics. And you have a master's degree in: 

  • a field of study that shows breadth and connection. For example, a Master's degree in Industrial Engineering & Management, Innovation Management, Transition Management or Industrial Design.


  • a Master's degree in a technical study, but you know and can demonstrate that you want to connect with other disciplines.

That does not mean other studies are excluded but those with a background in STEM and research experiences will have far more options within TNO.

What if my background is not included?

Then it seems that the TNO Trainee Programme may not be the best match for you. You can register for a job alert for your own background or check our other vacancies.

Can I contest the decision of the evaluators?

To be honest, not really. Matching the right candidates and our available spots is a puzzle where you can rely on the recruiters and research managers to keep your best interest at heart. In the end we all benefit from the best possible match.

I have a PhD, can I participate in the Trainee programme?

No, the trainee programme is for candidates who recently finished their Master studies. For PhD candidates, we offer the Talent Development Programme.
