I was contacted via email and asked if I could interview for a different role they thought was more fitting. However, for this role I was asked questions about software I never claimed to master and had not even mentioned in my CV. I struggle to understand why they thought I would be a better fit for this role instead of the one I originally applied for and never got any explanation when I asked for it.

It was a technical interview in python. I had to do some basic string manipulation, searching something in an array and creating an class and invoking some methods that I've created inside that class and explain some basic OOP.

There are two parts of the interview. First there is the test part in which they check you technical knowledge and then there is the second in person interview a few days later.
