Overall positive. Prepare for technical questions. Present your genuine self

Modeling and ML Knowledge, ML Implementation/Engineering System Design, Product Metrics and Analytical, Business Case and Strategy

What was one of your solutions?

Both reduce word down to base form. But stemming uses rough heuristics to reduce words to base, might not be an actual word, while lemmatisation uses vocabulary and morphological analysis return the dictionary form of a word, which must be a valid word. If speed is focused then stemming should be used since lemmatizers scan a corpus which consumed time and processing. If interpretability is concerned, then lemmatisation should be used since it returns a valid word.
