Machine Learning Engineer Interviews

Machine Learning Engineer Interview Questions

Companies rely on machine learning engineers to help design and improve the systems that allow their software to improve on its own, rather than being specifically programmed. During the interview process, be prepared to be tested heavily on both computer science and data science knowledge with an emphasis on recognizing patterns and trends. A bachelor's degree in computer science or a related field will be required.

Data Structures Round: They asked stock price fluctuation from Leetcode with a little twist in the question. The focus is on what Data Structure I choose, their trade offs and Time complexity. The code should be executable along with Unit tests in 60 mins. I had a Java Developer interviewing me, I did my solution in python. The interviewers will give hints through out the interview, thus felt like a brain storming session. The difficulty of the MLE interview is equal for an SDE role
