I applied for a Machine Learning Research Scientist (PhD) position. I did pretty well in the initial CodeSignal screening and passed all four test cases, but I did not move forward to the next stage. It seemed the role might have been leaning toward an internal candidate or my resume was not enough

A recruiter reached out to me and scheduled a technical screening interview, which consisted of two LeetCode easy/medium problems. After passing the screening, I moved on to the virtual onsite interviews, which included: 2 coding interviews (LeetCode medium/hard), 1 ML system design interview (focused on a binary classification problem), and 1 behavioral interview The interviewers were friendly and supportive throughout the process.
