The journey begins with an initial technical recruiter screen, followed by an in-depth phone interview with the hiring manager. This initial conversation focuses heavily on your past project experience and your foundational understanding of embedded systems. If you pass this stage, you will move into a series of technical coding rounds, typically conducted via Coderpad, where you will solve programming challenges in C++ while discussing low-level engineering concepts. The final stage is a comprehensive on-site loop consisting of multiple specialized rounds covering deep dive architecture, systems programming, and behavioral evaluations.

The timeline above outlines the typical progression from your initial application to the final offer stage. Candidates should use this visual structure to pace their preparation, ensuring they dedicate sufficient time to coding practice before the online rounds and system architecture practice before the on-site loop. While the process is rigorous, it is highly transparent, though candidates should anticipate up to a week for feedback consolidation between stages.
