Interview Process:

At Flawless, our team and interview process want to help you show your best self. We'll dive into past projects and simulate working together.

Our interview process is three interview rounds with some casual Zoom (or in-person) coffee in between to get to know each other:

- Recruiting Screen: 30-45 minute call with our recruiting team (We want to discuss your interests and motivations as well as the practical details and make sure that Flawless would be a good fit for you)

- Coding Interview: 60 minute Zoom. This will be a technical paired-programming task with one of our engineering team.

This is designed to be an open/pairing type exercise to assess your ability to parse simple requirements, translate those into code, and demonstrate your fluency with hands on coding.

- Team Interview: ~2 hours onsite Interview where you will meet a variety of your potential future colleagues (We will have specific sessions that focus on how you collaborate with others and your technical experience.)

Your Recruiter and hiring manager will be your main point of contact and prepare you for interviews. You'll meet 4 to 6 people from across the business. (We make sure that you have time in each interview to ask them questions). If we don't give an offer, we'll provide feedback!
