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.

8,210 machine learning engineer interview questions shared by candidates

The level of coding questions in the coding round was on the tougher side. There were two questions on graph of which one was a modification of finding the diameter of the graph. The technical round was on the easy to moderate side. There were three questions on data structures and algorithms and one SQL query to find the second highest employee salary from an employees table. One question was a variation of peak finding. Another one was a variation of Kadane's algorithm and last one was an open ended question on reading data from a file and finding frequency of elements. This led to the discussion on hash maps and collisions and multiple prevention strategies. There was a hiring manager round where I was tested on CS fundamentals and some behavioural questions. I was asked to explain the entire journey of a HTTP request and the OSI network model. There was a discussion on paging and memory management. I was also asked to explain types of polymorphism.
