Deloitte Immersive Online Assessment (IOA) and One Stop: Pass at Your First Attempt

Congratulations on successfully completing your earlier stage. Many applicants will not have reached this point, so you are already doing very well. Now it is time to take it to the next level. The Immersive Online Assessment or One Stop is an early gateway used by Deloitte to understand your strengths and thinking style.

Deloitte Immersive Online Assessment Preparation

After you receive your invitation, you will typically have a short window to prepare. Job tests can feel daunting, especially without Big Four experience. Bring your effort and curiosity and we will give you the structure, practice, and feedback you need to perform at your best.

Deloitte IOA and One Stop Competency Criteria

Deloitte designed the IOA and One Stop to assess you against their values and competencies. You will be measured on skills such as being motivated and committed, learning oriented, tech curious, a relationship builder and an effective communicator. You will also be assessed on resilience and adaptability, focus and efficiency, analytical thinking, creative problem solving and core cognitive ability.

Deloitte also asks every candidate to act with integrity. Complete assessments independently, use your own judgement, keep content confidential and be ready to explain how you prepared. Our training shows you how to prepare the right way while keeping everything compliant with Deloitte guidance.

Deloitte IOA and One Stop Assessment Details

Assessment partner. Deloitte works with Cappfinity as a specialist assessment partner. For some programmes you may still see tests built with providers such as Talent Lens and Kenexa, and a small number of service lines can continue to use Watson Glaser style critical thinking later in the process. We prepare you for all of these so you are covered whatever you face.

Modules you will see in IOA or One Stop

• Behavioural module. This simulates life at Deloitte and asks how you would respond in realistic scenarios. It is untimed but commonly takes around 35 minutes. Be authentic, use the information on screen and choose the response that best reflects how you naturally work.
• Cognitive modules. Numerical and verbal reasoning questions that look at how you work with data and written information. These modules record the time you take but do not stop you at a fixed limit. Each module usually takes around 12 minutes on average, so work both accurately and efficiently.

Practice from Deloitte. Deloitte provides open practice so you can get familiar with the platform:

• Overview and guidance page on the Candidate Zone here.
• Practice Behavioural Assessment made by Cappfinity start practice.
• Practice Cognitive Questions made by Cappfinity start practice.

What appears on screen. You will navigate tiles that introduce the organisation, define your contribution, explore challenges and encourage reflection. Information sources appear above the questions. Read them carefully and then answer every question. The progress bar helps you track how much you have completed.

Important. The Job Simulation is a later stage that focuses on behavioural skills in a project setting and can include written and video responses. This page is about the IOA and One Stop. Our separate Job Simulation page gives full guidance for that stage.

Legacy tests you might still meet

Some service lines and locations retain a short Watson Glaser style critical thinking test. Sections include Inference, Recognition of Assumptions, Deduction, Interpretation and Evaluation of Arguments. We keep this content in our course so you stay ready for all variants.
