What to expect at the group assessment

Group discussion
What does it mean?

It is a team discussion of the issue you have to solve working as a team with other applicants.
What's the point?

Recruiters assess your ability to find a middle ground, hold your own, work as part of a team. For instance, your team is tasked with launching a cutting-edge startup. At the same time, each team member has been given individual inputs to be taken into account by others.
What's the catch?

You might stop listening to the others and aggressively compete with them to get the recruiter's attention.

Role-playing
What does it mean?

A simulation of a real-life situation in a corporate environment, for example, a contingency, a nervous client making a plethora of corrections or attempting to explain to the manager why it's not possible to forecast the model effectiveness in ML.
What's the point?

The recruiters assess your problem-solving skills in the role-play scenario.
What's the catch?

Although it is important to get into character and to take on the role, your acting skills are not what is judged here. Centre on what you are saying instead of your acting skills.

Creative assignment
What does it mean?

An out-of-the-box task. You may find the task to be far-removed from your specialization. To illustrate the point: you graduated from the Materials Science Master's program and the recruiters ask you to draw blindfolded, only going by other candidates' cues.
What's the point?

This is an easy way to check your teamwork skills, lateral thinking, and the ability to solve non-trivial tasks.
What's the catch?

You have to come in mentally prepared. It's difficult to predict what the assignment will involve, however take your time to google it beforehand and take a closer look at the format.

Case study
What does it mean?

A complex industry-specific task. The task may include some extras: studies, diagrams, and data.
What's the point?

A case-study interview will assess your analytical thinking: the ability to process a large bulk of data, to distribute information, and to draw conclusions. What's more, your presentation and advocating skills will be judged.
What's the catch?

The case study offered may be for a completely industry to see if you can handle the new background data and right-away succeed in a completely new area.
