Junior Python interview: the candidate has a stronger grasp of OOP than is typical for a junior level

A mock interview for the role of Junior Python Developer, focusing on OOP and the inner workings of Python. We discussed classes, objects, metaclasses, inheritance, type(), dynamic class creation, as well as the magic methods __str__ and __repr__. Finally, there is a detailed analysis of the candidate’s answers and feedback not only on the technical aspects but also on soft skills during the interview.
