What Is the EY One Assessment?

Provided by Cappfinity , the EY One Assessment is designed to simulate real-life scenarios you may encounter while working at EY, providing you with a genuine insight into the organisation's actual work environment.

  • Job Preview - mimicking the different tasks and situations you will face through a day of work in EY:
    • Data Analytics - You will be presented with numerous sources of data, followed by a Situational Judgment Test (SJT) and written responses based on the data sources.
    • Delivering Results - An SJT in which you will be asked about your personal tendencies and how you will react in situations you may encounter in your position.
    • Forming Conclusions - Similar to Data Analytics, but one of the response questions is Recorded.
    • Making Connections - Similar to Data Analytics and Forming Conclusions, but both response questions are recorded.
  • Numerical Reasoning - Although not tested in the multiple answers format that is traditional to numerical reasoning, it will be assessed through the responses to the recorded and written questions.

Except for the pre-recorded interview, the EY One Assessment has no time limit, includes 24 questions and takes about 80 minutes to complete.

Let’s take a closer look at each of the sections!

Data Analytics

This section of the EY One Assessment is a combination of 1 situational judgment test (SJT) and 2 Written Response tasks.

You will be equipped with several information sources on top of the page and three questions underneath.

These data sources include customer feedback, financial reports, an email with a task, and data tables and graphs. They will remain at the top of the screen throughout the test, so you can return if needed.

While the SJT questions will try to assess how you feel about such a task, the written response questions will assess your ability to gather insights and summarize data from integrating the different information sources.

This section is untimed and takes approximately 20 minutes.

Let's take a look at one such Written response task. While this question includes numerical variables, the actual test also includes emails and verbal data sources.

View Explanation

The EY One Assessment will include several such questions, evaluating your ability to reach conclusions based on different data sources, summarizing and taking into consideration specific requirements from the colleague "handing" you the task. Solving such questions will require you to consider the person giving you the assignment, his role, and the different parties that your responses may influence.

Delivering Results

This section of the EY One Assessment focuses on SJT and aims to evaluate how well you fit in with EY's culture and values.

Your sole information source is an email, and you will be presented with a series of statements regarding a work-related situation.

You will need to rank the different response options according to how you are likely to act.

You will have 3 items to address.

There is no time limit, and it takes about 10 minutes to complete.

Let’s see how it looks –

Master the EY One Assessment

Successfully navigating the assessment's recorded and written response questions will require separating the chaff from the grain, offering concise and insightful answers while reading the situation, considering different parties affected by your actions, and fitting EY's core values.
Our detailed simulation will offer you the optimal preparation for dealing with such information overload.

EY Numerical Reasoning

The EY Numerical test, provided by Cappfinity, assesses your ability to understand, analyse, and interpret numerical information.

You will be presented with numerical data in the form of word problems, tables, charts, and graphs, and you will be asked to perform calculations based on this information.

The question format varies, with some being multiple-choice while others are open-ended, which requires you to enter the answer manually.

You are allowed to use a calculator, pen, and paper.

You will have 12 questions to answer with no time limit. It takes approximately 20 minutes.

The questions you will be asked in your EY pre-recorded interview can change according to the position and line of service you applied for. However, in most cases, they will address general information regarding your drives, inspiration within the position, and how you can contribute to the role and the organisation.

These questions can be –

  • Why are you interested in the role you applied for?
  • What strengths do you have that will help you to be successful in the role?
  • How would you stay motivated balancing work and learning at the same time?
  • What research have you done to prepare for the role?
  • Explain why you have chosen to apply for this location.

Although not an in-person interview, your recruiters will view your recording. As such, you need to address it like a conventional face-to-face interview, dress accordingly, keep eye contact with the camera, and be familiar with the organisation and the role you applied for.
