Questions posées lors d’un entretien d’embauche pour Full Stack Engineer (Java) chez Whatfix

Most of the questions were based on core Java concepts i.e Inheritance, Abstraction, Encapsulation and Polymorphism. One or two questions were on DSA. Those questions were based on simple array manipulation and tree. In the question on tree, the interviewer added new points and I had to change the code according to that. But, all the interviewers were helpful. One or two questions were also on my projects.
