I was contacted by a recruiter and given a take-home assignment, which I strongly believe was based on one of their real projects. The task was to design a RAG system for CBC data. I took it very seriously — spent four full days on it, completed everything, and even tackled all the optional parts. Despite that, after weeks of silence, I only received a generic rejection email from the recruiter with no feedback or explanation. It felt like they just wanted to use my ideas and code for their project rather than genuinely considering me for the role. Overall, it was a very disappointing experience.

Call with external HR to briefly discuss your experience. After that, online coding challenge (leetcode easy). If you pass that, talking with internal HR to set up a 1 hr meeting with the team, general technical/behavioral questions leaning on your previous experience.
