How does Netflix use collaborative filtering?

Collaborative filtering tackles the similarities between the users and items to perform recommendations. Meaning that the algorithm constantly finds the relationships between the users and in-turns does the recommendations. The algorithm learns the embeddings between the users without having to tune the features.
