THE PROCESS

Long interview processes are stressful and boring and that is not us 

We want to make sure that everything runs smoothly.

So here you will have three stage interviews:

1- A chat with one of our great recruiters.

2- A zoom chat with one of our Java colleagues where they will ask you detailed questions about your experience

3- A Face to Face interview (either in our office or via Zoom). During this interview, we will dig even deeper and you will have a pair programming task to do. You will also have a chat with our local director. 

But don’t worry; everything will be explained to you step by step by your recruiter.

A little tip for you during those stages: 

Collaboration is massively important to us, so don't hesitate to share your thoughts, ask questions, ask for help if needed, etc  

DIVERSITY & INCLUSION: 

Diversity and inclusion are key to a great workplace, and Adaptive is better when it’s more representative of the world around us. We want everyone to feel comfortable bringing their whole selves to work without any fear of judgment or negativity. 

All we ask is that our colleagues are respectful, collaborative, passionate about what they do, and have the skills needed to be successful in their roles.

Background check: the employment/engagement is subject to an acceptable background check that will be run by Adaptive
