In addition to this personalised coaching, we offer a series of online quizzes and tests on our website which faithfully reproduce the conditions of the official selection tests, well beyond the exercises available in this book. The book contains only a selection of the tests available, due to the large amount of content required to cover all the tests. For example, the book does not present certain specific tests, such as :

Abstract Reasoning Test which assesses your ability to deduce rules from abstract information and apply them to new situations, a key skill for many technical jobs requiring sharp logic.

Spatial Reasoning Test to measure your ability to visualise three-dimensional figures from folds, a useful skill in roles requiring spatial perception and sharp visual analysis.

Administrative Skills Test designed to test your ability to classify and check data quickly, essential for jobs where information management and organisation are crucial.

Planning Aptitude Test, which involves choosing the most efficient route based on a map and various constraints, requiring optimisation and rapid decision-making skills, often sought after in logistics and project management.

Technical aptitude test featuring technical drawings with specific questions, to check the ability to interpret diagrams, particularly relevant in engineering and product development fields.

Technical test or case study designed for specialist roles such as Data Analyst, Data Scientist, AI Developer, Statistician, and Data Manager, often in the form of MCQs or open questions focusing on data analysis or technical interpretation.

An assessment exercise and personality questionnaire associated with the oral interview, enabling us to measure the candidate's behavioural skills and personality traits, in order to check their suitability for the position and the working environment.

For complete preparation, our site offers a lifetime subscription that includes all these test modules, which are regularly updated to meet the requirements of government selection procedures. These resources guarantee you relevant training, so that you can prepare effectively for the different types of test you may encounter in the course of your career.

These missing tests, as well as other simulated tests, are available online to provide comprehensive preparation and considerably increase your chances of success.

BIBLIOGRAPHY

INTRODUCTION

In an increasingly competitive professional landscape, selection processes are becoming ever more demanding. This book serves as a comprehensive guide for those seeking to prepare for the various selection tests, whether administered by Hudson, Travailler.be (formerly Selor) or similar organisations.

The book covers a wide range of preparation exercises and practical advice, and is structured around three main categories of test: reasoning, behavioural skills and oral interview tests.

The content of this book is aimed at a wide audience. Whether you are preparing for tests organised by Hudson, Travailler.be or other selection agencies, you will find valuable resources here to help you in your preparation.

Selection tests have become a decisive tool for recruiters seeking to obtain a complete picture of candidates' skills, aptitudes and cultural fit. This book aims to provide you with all the keys you need to understand these tests and prepare effectively.

To give you an overview of the structure of this book, we begin with an in-depth exploration of numerical and verbal reasoning tests. It should be noted that, although spatial and abstract reasoning tests are often included in selection processes, we have chosen not to include them in this book due to their relatively lower demand compared to other types of test.
