Interview Process


After submitting your application, the team reviews your CV and statement of exceptional work. If your application passes this stage, you will be invited to a 15 minute interview (“phone interview”) during which a member of our team will ask some basic questions. If you clear the initial phone interview, you will enter the main process, which consists of four technical interviews:

 

1. Coding assessment in a language of your choice.

2. Post-Training Technical Session (2): This session will be testing your ability to formulate, design and solve concrete problems in post-training. It can be research or engineering, depending on background/experience. 

3. Meet the Team: Present your past exceptional work and your vision with xAI to a small audience.

 

Our goal is to finish the main process within one week. We don’t rely on recruiters for assessments. Every application is reviewed by a member of our technical team. All interviews will be conducted via Google Meet.
