There is a huge amount of variation in ML interview questions. You should Google "machine learning interview questions" to at least know the most common ones. But be ready to solve problems from first principles, such as designing a classifier or recommender systems. And be ready to explain ML projects on your resume in details, including tradeoffs you made in your development process. Ultimately, you should be able to do well on an ML interview if you actually know ML. If you don't, then memorizing answers probably won't help. If you do, then perhaps what you need most is interview practice and feedback to learn general interviewing skills and build confidence.
