Thales interview process, from the video interview to the assessment centre.

The UK graduate steps come from Thales's own ads for the 2027 intake, posted in October 2026. The French steps come from Thales's French careers page. Details marked as reported come from candidates on Glassdoor, The Student Room and Reddit, and from prep sites, read on 5 October 2026.

For UK graduates and apprentices, Thales's own ads say candidates who pass the online tests are invited to a video interview, and those who progress from it attend a virtual assessment centre. Thales says the assessment centre may include presentations, group exercises and competency-based interviews. Candidates describe the day as a group task plus two separate interviews, one on competencies and one technical. For the 2027 intake, assessment centres run from February to May 2027.

• The online tests: Thales does not name the provider. Prep sites report numerical and logical reasoning tests, with a technical test for some roles. Practise timed questions and read the invitation email for the exact tests.
• The video interview: You record answers to set questions. Reported themes: why Thales, why this role, a hard problem you solved, and how you take feedback. Give each answer a clear situation, your action and the result, and keep it within the time.
• The presentation: Reported as part of some assessment centres, sometimes prepared as a group. Keep to the time, give one clear recommendation, and be ready for questions.
• The group exercise: Assessors watch how you work with others more than whether the group finds the perfect answer. Listen, build on other people's ideas, keep track of time, and help the group reach a decision.
• The competency interview: Candidates report follow-up questions on each example. Prepare five or six stories, such as teamwork, a hard problem, feedback and a mistake, and know each in detail.
• The technical interview: Reported as a separate interview on the discipline of the role, often starting from your degree and projects. A graduate machine learning candidate said the follow-up questions were especially hard in the technical interview. Know your final-year project inside out.

Calibrd can rehearse the video interview questions and the competency and technical interviews aloud, with follow-up questions. It cannot run the timed tests or the group exercise.

Thales sums up its purpose as building a future we can all trust, and its about page explains that trust depends on security, ethics and responsible technology. In interviews this shows up as:

• Rigour: following proven methods and documenting your work, because people's safety can depend on it
• Trust and discretion around sensitive customers and information
• Keeping people in control of the systems you build, which Thales calls trusted AI
• Working well in a team, which the assessment centre group task tests directly
• Comfort with defence work and with the security checks that come with it

These are the themes candidates report from Thales graduate and engineering interviews in the UK and France. The questions are our own practice questions in the style candidates describe.

The £34,000 is posted in Thales's 2027 Software Engineering Graduate and Systems Engineering Graduate ads, with performance-related pay rises, a pension and 37 hours a week. French ads give no figure. The UK graduate range is from Glassdoor, the French software engineer median is from Levels.fyi (about 306 reports) and the junior engineer average from Glassdoor France, all read on 5 October 2026.

1. Check the security rules before you apply: UK graduate roles need the permanent right to work in the UK and, typically, five years of continuous UK residence for SC clearance.
2. Practise timed numerical and logical reasoning tests, then read your invitation email for the exact tests.
3. Prepare five or six competency stories and say each one aloud, ready for follow-up questions.
4. Know your final-year project or internship in depth: the problem, your choices, your tests and the limits.
5. For the group exercise, practise listening, summarising and moving the group to a decision.
6. In France, read the job ad line by line: candidates say the technical questions follow it closely.
7. If the ad mentions habilitation, ask the recruiter early how long the procedure usually takes for that role.
8. Have an honest answer ready on why you want to work for a defence and aerospace company.

This guide covers Thales's graduate and apprentice hiring in the UK and its engineering, intern and apprentice hiring in France. Other countries and business units can run a different process. For management and leadership roles the loop is similar but the bar shifts to people, delivery and strategy, so pair it with the leadership interview prep hub. The bar for your exact role comes from the role-by-role guides, and the prep that actually transfers is spoken, so run a mock interview before the real one.
