Accenture Application Development Associate interview questions

What is method overloading and how would you mediate this issue?

The interviewer asked for my introduction. Then asked about my 4th year project. I told them about my project, which was about credit fraud detection using classification algorithms. They proceeded with questions related to that like- From where do you get the dataset for the project? What steps did you follow for making ML model and what are the merics you used for evaluating your model.
