PayPal Sr Machine Learning Engineer interview questions

Interview was divided in 3 parts 1. Projects review - Did not go too deep. Asked which was most challenging 2. ML breadth - Multiple theoretical questions 3. DSA question - Medium level

Took the initial Programming technical interview as practice despite not wanting the commute or the significant pay cut it would entail. Interviewer was professional, but if a company wants to ask questions like this without giving any interview prep, they should at least be offering competitive pay.
