Tech Stack: NodeJS, React, Swift, Typescript

Engineering Interview Process

  1. A Introductory Phone Call 

  2. A Small take home project - varies by role. 

    1. Typically a very simple project on the platform most related to the role. (2-4 hours)

  3. Technical Interview - One of the following:

    1. Similar to an in person code review, the technical interview is a chance to talk through what decisions you made in the project, understand why you made them, give you feedback on things we saw that we did / didn't like and have a conversation about those. This is less about having the "right" answer and more about seeing what it is like to work with you, and give you the same chance to preview what it would be like to work with us. 

    2. For high experience roles, or roles that don't make sense to have a take home project for, a technical panel interview instead of the Technical Interview. The goal here is really to get an understanding of what it is like to work through problems with you, and give you a chance to see how we like to work. These will be very much related to the actual problems that we are looking to have the person in this role solve. There is no whiteboarding, irrelevant technical "gotchas" or anything you would need to memorize in advance. We'd like this to be as related to the job itself as possible. 

  4. Meet the CEO 

  5. Meet the team
