SHL test - how to prepare and why is it important?

Recruitment is a complex process, its elements strongly depend on the hiring position and the competencies we need on board. From the recruiter's perspective, the CV itself often doesn't tell enough about the candidate, we rather treat it as a good starting point for further discussions. However, the moment of the verification of soft, analytical skills and substantive knowledge comes later. One of the stages that often appear in recruitment to Tidio is the SHL numerical test. Its main purpose is to test the candidate's analytical skills and logical thinking abilities.

How did we come up with the idea to use the test in the recruitment process?

The idea has the roots in how the whole organization works – so being data-driven. This test is not intended to verify how quickly you can cope with mathematical operations, rather it is to check if you are able to make efficient business decisions based on data in a quick time. Even if your daily work is not based on data analysis, the aspect of logical thinking is strongly important to us. Such a skill helps us to not only set the right goals in new projects but also optimize the existing ones. Even the recruitment process itself can be a good example here. Thanks to monitoring the sources where the candidate has heard about Tidio for the first time, we are able to choose channels where we publish offers that bring us the best results.

But back to the test itself ... What does it look like and how to prepare for it?

The test consists of 18 questions, and you have 17 minutes to complete it. The general premise of the analytical test is that you should spend 30 seconds to 1 minute solving each task.

If you have never taken a similar test before, I recommend checking the example tasks 👉 . This shows you closer the specifications of the test. It is best to take these tasks in stride, without imposing any time limits on yourself.

The good tip would also be to analyze the types of tasks and learn what is the best approach to solve them. You can expect tables, graphs, comparisons between data. The questions can be different, in some of them, it is important to perform a mathematical operation, in others all it takes is a moment of reflection and elimination of options that don't make sense.

When you get familiar with the sample tasks, it would be wise to take the actual test... My top advice: don't stay too long on a question that you can't find a solution to. Sometimes it is worth sacrificing one question for an additional few minutes to get through to the end of the test. This is supported not only by my experience but also by what I’ve heard from other candidates. In addition, it is good to bear in mind the time left until the end of the task. The most common problem with the test is not its difficulty level, but the very limited time that is given to complete it. 


I hope that after reading this text, you will not only know how to best prepare for the test, but primarily you will be aware of why this stage in the recruitment process is so important to us. An additional benefit is that each candidate who solves a test receives a summary of their results from us. So it is also extra feedback for you. To sum up – be brave, trust your abilities and take the test! It will take just a couple of minutes, so don’t worry too much about it ;)
