We carefully review each candidate's application for the role. If there is a match, we'll reach out to invite you to the next stage. Our hiring process will generally follow this format:

1. Technical Test -  You'll receive a short take-home technical quiz via email. This test is designed to reflect the kind of work you'd be doing and will give us insight into your technical skills and problem-solving approach.

We'll discuss your past experience, career goals, and the role in more detail. This interview will have a behavioral component, focusing on how you've handled past situations.
3. Onsite Interview -  The final interview is with our Engineering team at our Toronto office (296 Richmond Street West). You'll meet with our Director, Engineering and a Team Lead for a deeper dive into your technical background and the role's specific responsibilities. This will be a technical interview, so come prepared to discuss your experience and showcase your skills.
4. Offer Stage -  If everything aligns, we'll extend an offer to welcome you to the team. Please note that all offers are contingent upon successful reference and background checks.
