Advanced Reasoning Assessment
This is a timed reasoning exercise used in our interview process. Please read the instructions below carefully before you begin. They explain how the test works and what we are looking for.
We do not expect you to solve every question. Almost no one finishes them all, and that is by design. We are far more interested in how you reason than in how many you get right. A thoughtful approach to a hard problem tells us more than a lucky guess.
Tools like ChatGPT, Gemini or Claude will not help you here. The questions are designed so that there simply is not enough time to copy them out, prompt a model and transcribe an answer. Your own clear thinking is what counts.
So you know exactly what counts before you begin. Each question is graded on two parts, and they do not carry equal weight:
The explanation you write for each answer is the larger part of your grade. Clear, sound thinking is what we are really looking for.
Whether the option you choose is correct counts too, but on its own it is the lighter half of the score.
To keep the assessment fair for every candidate, this is a monitored exercise:
The timer starts the moment you begin.
