The company is in a growth stage and as the company scales, there are processes that are scaling with it. This takes time, so be patient and open-minded. The company value, "We love what we do and fix what's broken" will be your guiding light as you enter this new chapter in your professional journey.
The Interview and Hiring Process is well structured, albeit a little stressful, but that's true for any hiring opportunity. Leticia, Kaitlyn, and Alexia do an amazing job of shepherding you through each phase (Phone Interview > In-Person > Demo > Final Team Interview).
Bonus Advice: The emails the People Ops Team will send you will outline EXACTLY how to nail each stage of your hiring journey. Just "showing up" will not see you advance to the next stage.
