Machine Learning Engineer Interview Experience - Canada
Process
I received a phone call from a recruiter regarding a background check, and was then invited to the next technical interview.
The recruiter was very helpful and provided detailed instructions for interview preparation, including specific coding problems to practice and the key skills the interview would focus on testing.
However, during the interview, the interviewer did not seem to prioritize time complexity, thinking aloud, or optimization.
