Migrating our app to Vite for faster build times. Micro-mono repo to scale out different services using the same application. Our application is a multi-tenant SaaS product with support for isolated databases and compute instances, meaning each tenant gets a dedicated database (isolated data) and dedicated compute (highly scalable) to process requests. We built a custom API router (like DNS) to redirect requests to the right destinations. We primarily write code in Ruby and use Rails for our backend framework and we use React (with Ant design + Tailwind CSS) for the frontend applications. We run our Rails applications on Cloud Run and serve our frontend applications using a mix of Firebase and Cloudfare Workers, they communicate primarily through GraphQL. Our custom API router is built on Cloudflare Workers and KV store for high availability and performance. We use managed Postgres (Cloud SQL) and Workers KV to store application data. Interview Process What’s the interview process like? Quick 45-minute screening interview to make sure we are on the same page. Here we try to briefly understand cultural fit, where you’re at, what you’re optimising for, strengths and weaknesses, relevant experience, etc. 1-1.5-hour deeper interview with the functional lead. There may be some overlapping questions here because we don’t like comparing notes between interviews to keep the process independent (for technical roles). 6-8 hour practical interview (for technical roles). Reference interviews (both from you and us, finding mutual connections). Optional, but we also like to have a “cultural immersion” with the rest of the team over a meal/drink if possible.
