Sitting in a group, and given about one hour to answer a questionnaire with the questions I submitted here. This written test served as a basis for the 1:1 interview afterward.

1. Explain Singleton. Implement this class.

2. Write code to check if a linked list is circular.

3. Some basic questions about OOP and polymorphism.

4. Some questions about threads:

   • Difference between threads and processes.
   • How can they communicate with each other?

5. Some questions about Java's garbage collector and memory model.
