Machine Learning Interview Questions
"To get a job in machine learning, you must have the programming and mathematical knowledge to create artificial intelligence that is capable of learning new tasks without being explicitly coded. In an interview you may be asked about your experience with pertinent coding languages such as Java and C++ as well as with writing algorithms. The interview will be comprised mainly of technical questions that test your knowledge of the fundamental concepts of machine learning such as data mining and signal processing."

construct a join between 3 tables with some constraints
wavenet, time seriers
I appreciated the depth to which various interviewers wanted to understand what I was looking to get out of a role with PhysicsX, and ensure that we were a good fit for each other.
This was effectively a ML system design question for a entry level position. It's not hard to guess what one could be given that they are effectively trying to solve problems in supply chain. Hint: Try to look up ML system design questions at companies like Uber.
Technical coding test using HackeRank
For hacker rank I solved two basic programming questions. One about accessing an array and another filling missing data with averages.
Asked some basic Python questions about syntax and generators. Take-home assessment was about 5 hours long and consisted of a supervised ML problem. Incorporated skills that they looked for in an ML SWE.
Tell me about a time when you learned a new technology to solve a problem.
How to vectorise a certain set of operations using Numpy.
