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. Systems hands-on: Demonstrate practical skills in a live problem-solving session.


3. Project deep-dive: Present your past exceptional work to a small audience.


4. Meet and greet with the wider team.
