An HR call initiates the process, then a take home challenge relevant to the team is given. After it is returned, there is an interview with the hiring manager. If everything goes well, further technical interviews (4) with different people are scheduled and a final decision is taken.

Take home challenge was about graph theory and applications, like register allocation. Interview technical questions revolved around knowledge of concurrency, low level constructs, memory allocation, and the general day to day processes and work behavior.

Colloquio
Overall, I had a very positive experience. The process was a bit long (a little over a month), but it also included the Easter holiday period in Europe/Montreal.
The process was: HR phone screen, hiring manager interview, take-home assignment, technical round, and three virtual onsite rounds (Product, Behavioral, and ML knowledge), followed by the final decision.
There was only one coding assessment, in take-home format. The algorithm/design pattern/GitHub parts were quite basic. There was also some web development content (CSS/HTML layout), which was more challenging for me since that is not my primary area.
I then had a technical round that focused mostly on past experience rather than the take-home assignment itself.
In the virtual onsite rounds, the last ML round covered many ML topics. I prepared a lot and was able to answer many of them, though not all. The interviewer was very helpful and willing to share knowledge, which I appreciated.
The interview process began with a phone call with a recruiter, followed by a Zoom technical interview with the team leader, who asked about my experience. After that, I had two system design interviews, and finally an HR and senior manager interview.

Colloquio
I started with an initial conversation with Recruiter team, where the process was clearly explained to me. After that, I quickly moved to a high-level discussion with the hiring managers about the team’s architecture and specific needs.
I was then guided into several technical interview rounds — about four sessions, each lasting around 45 minutes. These included both team members and experienced professionals from outside the team, with diverse backgrounds. Almost every stage included a coding assignment component, as well as high-level discussions and deep dives into relevant parts of my background.
The entire process took around four weeks in total: about two weeks for the interview stages to be scheduled and completed, and another two weeks before I received the official result. Throughout the process, interviewers were intelligent, collaborative, and supportive.
I enjoyed the experience and gained a clear understanding of what the role involves. The challenges were fair and engaging, without feeling overwhelming. I was very happy with the outcome.
