Machine Learning Engineer Interview Questions
6,174 machine learning engineer interview questions shared by candidates
Coding questions similar to leetcode medium level and ML questions were reasonable for the principal level. Interview process was reasonable overall.
Design a ML model that can price items in the marketplace. Some items may have never been seen before.
More Technical questions Need to be strong in Analytical and mathematics Need good communication
Take-home assignment: You will have 4 hours to complete it. Your solution will be evaluated through a series of tests that measure accuracy and performance, and it must handle a wide range of possible cases effectively.
Comment faire du fine tuning d'un LLM ?
Describe RAG , how it works
standard format with Leetcode type questions with test cases, a couple of design rounds. However expectation setting was very poor.
Reverse the string Several ML questions - what is bias and variance, what is the difference between classification and regression, What is the effect on the output feature maps of the convolution layer that follows a max pooling layer. Why do we want a maxpooling layer. When to use a confusion matrix. What is the difference between precision, recall and F1. what is focal loss, what is dice loss. ML System Design (Facial recognition system) - think about clustering, dimensionality reduction, database storage, approximate nearest neighbor search, reducing database lookup time with horizontal scaling. Also think about feature/concept drift detection and rectification. Talk briefly about knowledge distillation, model quantization and pruning. Data engineering question - how would you remove duplicate images? Hash the images using a fingerprinting algorithm using DFT. Similar to how shazam's audio fingerprinting works. Now you have reduced the problem to removing duplicate fingerprints. If you type "image hashing" in google, a lot of academic papers with noise robust algorithms will pop up.
