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 there will be three stages to ascertain the required skills:

1. A chat with one of our great recruiters.
2. A zoom chat with one of our Java colleagues where they will ask detailed questions to determine a skills fit
3. A Face to Face interview (either in our office or via Zoom). During this interview, we will dig even deeper and there will be a pair programming task to do.

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

A little tip for you during those stages:

Collaboration is massively important to us, so don't hesitate to 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.

Consultants will find our team 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
