Eli lily - Electronics clinical outcomes assessment (ecoa)programmer

So started with my introduction then he shifted to my internship based questions and asked about the type of project and who was i working under and how many team members, then he asked bout classes and inheritance and asked me to code in any language I'm comfortable with, what is bubble sort, then asked me a palindrome code and after this he asked about how to count the frequency of words in a sentence, i fumbled and said using for loops and array whereas hashmaps are the correct choice, then he asked about AI/ML and classification using k means and clustering then asked about linear, logistic, polynomial regression.
