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.

Top Machine Learning Engineer Interview Questions & How to Answer

Question 1

Question #1: What are the most important algorithms, programming terms, and theories to understand as a machine learning engineer?

How to answer
How to answer: Be prepared to talk about things like Type I and Type II errors, supervised and unsupervised machine learning, ROC curves, and other key parts of machine learning. Employers want to know you have a strong knowledge of the technical aspects of the job position.
Question 2

Question #2: How would you explain machine learning to someone who doesn't understand it?

How to answer
How to answer: Sometimes machine learning engineers have to work with people who aren't familiar with the technical aspects of the job. Use this interview question as an opportunity to show your strong knowledge of the position and your communication abilities.
Question 3

Question #3: How do you stay up to date with the latest news and trends in machine learning?

How to answer
How to answer: By talking about how you're up to date with the latest news and trends in machine learning, you can show an employer that you're engaged in the industry, a skilled researcher, and self-motivated.

8,202 machine learning engineer interview questions shared by candidates

you are supposed to answer 10 questions with one minute time given for each. I had 2 -3 questions on concepts of machine learning and rest of them were from concepts of computer science. Things like tuple, duck typing, generator , xrange etc. After that you will have to finish a small machine learning project in your choice of language. Interview process is pretty thorough.

What would the classes and methods for a "Hit Point Management" system look like, that has the following functions - increment(user, value), decrement(user, value), getHitPoints(user) and killAll()? The first two methods add/subtract the user's hit points by the amount in value. getHitPoints() returns a user's hit points and killAll() sets all users' hit points to 0. What are the run times of the methods? How can you make all the methods run in O(1)? Note: If we set the hit points data structure to null, or re-initialized it to a new structure, the garbage collector still has to do the work of going through all the users.
