MI6 sets an online situational judgement test. The Secret Intelligence Service lists it as stage three of eleven for Intelligence Officers, and asks Business Support Officers to complete two online tests instead. What SIS does not publish matters just as much: it names no test publisher, and gives no duration, question count, section structure, marking rule or pass mark for any test anywhere on its careers site. Any page quoting you a timing for an MI6 test has invented it.
Below is every stage SIS actually publishes, route by route, and practice in the one format it names.
MI6 Tests And Assessments
SIS names its online exercises only as stages in a process. It never names them as products, and it never describes what is inside them. That is the honest starting point, and it is why the stage lists below matter more than any claim about question counts.
Across the five career routes SIS publishes, these are the online stages it names:
- Intelligence Officers: "Complete an online situational judgement test." The only description SIS gives is one line: "You will be presented with hypothetical work-based scenarios and asked to make judgements about possible responses." A later stage is an online analysis and reporting exercise, which SIS does not describe at all.
- Business Support Officers: "Complete two online tests." Nothing further is published about either.
- Technologists: "You may be required to complete an online test, dependent on role."
- Language Specialists: no online test. Instead, a language testing day.
- Corporate, Trades and Services: no online test at all. Where the role calls for it, a technical interview takes that slot.
Practising The Format SIS Names
A situational judgement test puts you in a short workplace scenario and asks you to judge responses to it, usually either by rating how effective a single response would be or by ranking several from most to least effective. SIS does not say which of those two styles it uses, how many scenarios there are, or how long you get. So situational judgement practice is worth doing for fluency rather than for format: reading a scenario quickly, spotting who is affected, and judging responses by their consequences rather than by how well-intentioned they sound.
The online analysis and reporting exercise is the stage we can tell you least about, because SIS publishes nothing beyond its name. General groundwork in verbal reasoning and numerical reasoning exercises the skills that name implies, drawing conclusions from written material and from figures. Treat that as general preparation. It is not the MI6 exercise, and nobody outside SIS knows what is.
What SIS Says About Preparing, And About Assistance
SIS neither recommends nor discourages preparation material. It says nothing about it either way, so treat any site claiming an MI6 endorsement as making it up.
It does publish one hard rule. The online test stage "must be completed without the use of AI or any other third-party assistance", and the same prohibition covers interviews, automated video interviews, written exercises and assessment centres. Preparing beforehand is treated differently: SIS says using AI to rehearse answers to potential interview questions in advance is "completely optional and not expected", and that "we don't use AI to make our hiring decisions". The guidance is on the SIS site.
MI6 Application Process
There is no single MI6 application process. SIS publishes a separate stage list for each career route, and the lists do not match: eleven stages for Intelligence Officers, seven for Technologists, six for Business Support Officers, seven for Language Specialists, and seven for Corporate, Trades and Services. Four of the five carry the same line: "After each stage we'll assess your suitability before you go onto the next stage."
So the first thing to settle is which route you are applying to, because the answer to "how many stages" changes with it.
Intelligence Officers, Eleven Stages
SIS says this process "is rigorous and the time from application to joining can be over 12 months".
- Register online.
- Complete a short, initial eligibility application.
- Complete an online situational judgement test.
- Fill out a comprehensive application form including some scenario-based questions.
- Complete an online analysis and reporting exercise.
- Complete an online drugs test.
- Attend a virtual interview including a roleplay exercise.
- Attend a two-day assessment centre in London.
- Receive a conditional job offer, dependent on passing security vetting.
- Security vetting, which SIS says "can take around six months and vetting approval is not a given".
- Receive a formal job offer.
The Other Four Routes
- Technologists, seven stages: register, online application form, an online test where the role requires one, a one-day assessment centre, conditional offer, vetting, formal offer.
- Business Support Officers, six stages: register, online application form, two online tests, conditional offer, vetting, formal offer. There is no assessment centre on this route.
- Language Specialists, seven stages: register, online application form, a language testing day, a one-day assessment centre, conditional offer, vetting, formal offer.
- Corporate, Trades and Services, seven stages: register, online application form, a technical interview where the role requires one, a one-day assessment centre, conditional offer, vetting, formal offer.
SIS lists a route for experienced hires alongside these five. It publishes no stage list we can quote for it, so we will not describe one.
How Long It Takes
SIS publishes three different figures and they do not agree with each other. Rather than pick a winner, here is each one with what it actually covers:
- Around six months, for security vetting alone. This appears on all five careers pages, with the caveat that "vetting approval is not a given".
- Between nine and twelve months for the full vetting process, on the MI6 FAQs page.
- Over twelve months from application to joining, for Intelligence Officers specifically.
Whichever applies to you, this is not a process you rush. Do not resign from anything until the formal offer arrives, which is the eleventh stage, not the ninth.
The MI6 Interview And Assessment Centre
SIS runs competency-based interviews and describes the format precisely. "A competency-based interview is timed and structured", built on nine competencies grouped under three themes, Future, People and Delivery, with "around five to ten minutes per question".
It is also honest about the limits of preparation: "we can't tell you exactly which competencies we will assess at the interview". Prepare examples that can be angled at more than one competency rather than scripting one answer per competency.
For the answers themselves SIS recommends STAR-L: Situation, Task, Action, Result, Learning. The Learning step is the one candidates most often drop, and it is the one that turns a description of an event into evidence of judgement.
The panel and assessment stages differ by route. Intelligence Officers face a virtual interview including a roleplay exercise, then "a two-day assessment centre (AC) in London", which SIS calls "a rigorous scenario-based series of exercises designed to replicate the different IO roles". Technologists, Language Specialists and Corporate, Trades and Services candidates attend a one-day assessment centre. Business Support Officers attend none.
MI6 Eligibility And Vetting
SIS publishes its eligibility rules plainly, and several of the rules people repeat about MI6 are not among them.
- Nationality: "You need to be a British Citizen."
- Dual nationality is allowed. SIS: "If you hold dual nationality then one component will need to be British." There is no requirement to have a British parent, and no rule on the SIS site requiring you to give up a second passport.
- Age: "You can apply from the age of 17 years", though you cannot start before your eighteenth birthday.
- Residency: seven of the past ten years lived in the UK. Studying overseas, and Armed Forces or Diplomatic service overseas, count as being in the UK.
- Where you apply from: "You should only launch your application from within the UK."
- Degree: a minimum of a 2:2 in any subject, for Intelligence Officers. It is not a blanket MI6 requirement.
- Drugs: "All MI6 staff and contractors are subject to a no drugs policy", running from the moment you submit the application. Past use is not an automatic bar, but SIS says it is "important to be open and honest about your drug/substance use during the vetting process", and that "you may be tested for drug use should your application proceed".
Developed Vetting
Every offer is conditional on vetting. SIS: "you will need the highest security clearance, known as Developed Vetting", "a process everyone in the UK Intelligence Community goes through". It involves detailed questionnaires, referees agreed in advance, and an interview covering "family, friends, finances, health, relationships and lifestyle".
Three things SIS publishes that are commonly got wrong:
- "Having foreign national contacts does not mean you cannot hold Developed Vetting status."
- No feedback is given if vetting is unsuccessful.
- An existing Developed Vetting clearance from another department may shorten the process, but does not remove it.
Developed Vetting is one level in the national scheme. UK Security Vetting sets the current levels out on gov.uk: Baseline Personnel Security Standard, Accreditation Check, Counter Terrorist Check, Security Check, Enhanced Security Check, Developed Vetting, Developed Vetting renewal, and Enhanced Developed Vetting, the last being "required for a very small number of agreed, specific posts". The Baseline Personnel Security Standard is a pre-employment screening standard rather than a clearance, which is why counting "levels" tends to mislead.
Travel
SIS "strongly advise that you do not book new travel to Russia, Belarus", China including Hong Kong, North Korea or Iran while you are applying, and warns that "travel to or through these countries can impact vetting outcomes". If travel is already booked, SIS asks you to contact its recruitment team.
What MI6 Is And Who It Hires
In its own words: "We are SIS, the UK's Secret Intelligence Service, better known as MI6." It is the UK's foreign intelligence service and it is accountable "under the responsibility of the Foreign Secretary". MI5 is the domestic service, answering to the Home Secretary, and describes its job as protecting "the UK against threats to national security". MI5 confirms the wider shape: it works with "the UK's other intelligence agencies, SIS and GCHQ".
SIS quotes its statutory purpose from the Intelligence Services Act 1994: to "obtain and provide information about the actions or intentions of people outside the UK", limited to national security, the UK's economic well-being, or the prevention and detection of serious crime. That Act was also "the first public acknowledgement of the existence of both MI6 and GCHQ". Before it, SIS says, "our existence was not publicly confirmed until 1994".
The Career Routes
SIS's careers section lists five routes with published processes, alongside a route for experienced hires:
- Intelligence Officers
- Technologists
- Business Support Officers
- Language Specialists
- Corporate, Trades and Services
Intelligence Officer work itself splits into four business areas: Case Officers, Operational Managers, Targeters and Reports Officers. SIS says training "will be focussed on the Case Officer role". Its description of the job is worth reading before you apply: IOs "work in the UK and overseas to recruit, talk to and task people who can help us find out secret information".
MI6 Myths Worth Dropping
Several of the things said most confidently about MI6 are contradicted by SIS itself.
- An "MI6 agent" is not an MI6 employee. SIS is explicit that its staff are Officers, and that the people those Officers recruit as sources are the agents. In its own words, IOs recruit people who can help find secret information, "and we call these people agents".
- There is no fitness test. SIS: "There are no fitness standards for joining SIS." The work "is about human relationships, technology and critical thinking, rather than jumping out of helicopters".
- Most Intelligence Officers are not firearms trained. SIS puts it plainly: "The majority of IOs are not firearms trained."
- Bond is not the model. SIS's own line: "James Bond is a fantastic character, he wouldn't make a good MI6 team member."
- The head of MI6 is 'C', not 'M'. Blaise Metreweli CMG became the eighteenth Chief in June 2025, having previously been Director General Technology and Innovation, the role known as 'Q'.
- Tattoos are fine and there is no formal dress code. Reasonable adjustments are available at any stage, and travel expenses can be reimbursed.
Tips To Get Hired At MI6
1. Check The Eligibility Rules Before Anything Else
British citizenship, seven of the last ten years lived in the UK, and an application launched from inside the UK. Dual nationality is fine as long as one component is British. If you fail one of these, no amount of preparation changes the outcome.
2. Practise The One Format SIS Names
Situational judgement is the only test type SIS names by title, and it is a numbered stage rather than an optional extra. Get comfortable reading a scenario, working out who is affected, and judging responses on their consequences.
3. Build Five Or Six Stories, Not Nine Answers
SIS will not tell you which of its nine competencies it will assess. Prepare a small set of substantial examples you can angle at several competencies, structure them with STAR-L, and make sure each one has a real Learning step.
4. Protect The Application Itself
SIS advises a separate email address with no identifying features, and asks that you discuss the application with nobody beyond a partner or close family member, and never on social media. It also asks you not to book new travel to the countries listed above. Discretion is being assessed from the first click.
5. Plan For The Long Version
Vetting alone is around six months, and for Intelligence Officers the whole thing can run beyond a year. Keep your referees warm, keep your current job, and expect gaps between stages.
