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.

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

4. Meet and greet with the wider team.


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.

Annual Salary

The annual salary will be negotiated in a personal interview.
