Backend Team Final Interview Stage (Remote Edition)

🤝 Backend Team Final Interview Stage (Remote Edition)

During the next few weeks as we encourage all staff to work from home, we'll be trying out a new "final stage" of the hiring process.

Typically, we'd invite the candidate to the office to meet members of the engineering team in person, have lunch, and chat with the hiring manager.

The hard part (technical testing) is over and the focus is on getting to know each other. As such, our remote version of this process should focus on:

  • Social activities.
  • Letting the candidate see us working in-situ.
