MLE coding rounds (UK)

I’m a data scientist transitioning to ML-AI Engineer roles. What kind of coding questions-rounds should I expect? I’ve heard that it’s a mixed bag, can be leetcode, can be Pytorch,tf for all ML related I’ve also heard about building ML concepts-algos from scratch using numpy etc. Or even an ML pipeline with data preprocessing, modelling, evaluation. What are the most common practises you’ve come across? Is there at all a coding round? I’m in the UK so I’m not sure if things are different compared to the US.
