1. What is a Full Stack Engineer at monday?

A Full Stack Engineer at monday is a critical role that sits at the intersection of complex product development and high-scale system architecture. You are not just writing code; you are building the core components of a platform that millions of users rely on to manage their daily workflows. Your work directly influences how teams collaborate, organize tasks, and automate processes across the globe.

This role is unique because it demands a deep connection to the product. You will be expected to understand the monday ecosystem—from the front-end user experience of draggable boards and real-time collaboration tools to the back-end infrastructure that handles high-concurrency requests. Success in this position requires a balance of technical rigor, architectural foresight, and a genuine passion for building intuitive, performant tools that solve real-world user problems.

2. Common Interview Questions

The questions you face at monday are designed to mirror the actual challenges their engineering teams encounter. Rather than relying on abstract theory, interviewers prioritize problems that test your ability to build scalable, functional features.

Technical & Product-Centric Coding

These questions assess your ability to translate product requirements into clean, efficient code. You will often work on problems that are simplified versions of features found within the monday platform.
