With over 1000 clients worldwide, we have been deploying solutions for major projects for more than a decade – all made possible by an international team of 7,600 talents across 5 continents and more than 60 countries. Our solutions focus on four different business areas: Information systems and digital, telecommunications, life sciences, and engineering. We aim to create and develop a talent community where all team members can realise their full potential. Amaris is your "stepping stone" to cross the rivers of change, to meet challenges, and to successfully complete all your projects.

At Amaris, we are committed to offering our candidates the best possible recruitment experience. We seek to get to know and understand our candidates better, challenge them, and provide feedback as quickly as possible. Here is what our recruitment process looks like:

First contact: Our process usually starts with a brief virtual/telephone conversation to learn more about you! The goal? To get to know you, understand your motivations, and ensure we offer you the position that best suits you!

Interviews (on average, the number of interviews is 3 – but this may vary depending on the seniority level required for the position). During the interviews, you will meet members of our team: your future manager of course, but also others you will work with. These interviews will allow us to learn more about you, your experience, and your skills, as well as about the role and what will be expected of you. Of course, you will also get to know Amaris: our culture, our history, our teams, and your career opportunities!

Case study: Depending on the role, you may be asked to take a test. This could be a role play, a technical assessment, a problem-solving scenario, etc.

As you know, every person is different and so is every role in a company. That is why we must adapt accordingly, so the process may sometimes be somewhat different for each candidate. That said, we always put ourselves in the candidate’s shoes to offer the best possible experience. We look forward to meeting you!
