A recruiter approached me; they found my profile on Naukri. They scheduled the interview for a couple of days later. The interview round was online and included a "brief yourself" section, followed by direct technical questions on C, C++, OOPs, linked lists, pointers, and communication protocols.

Siemens:

1. Inheritance using private, protected, public for child class: What is the scope for all?

2. Can a private parent class be accessible by a child class? Yes/No. If yes, then how? If no, then why?

3. C program on a double linked list to find the minimum of all lists using a double pointer.

4. Pointer to pointer: What is the output?

5. Socket programming: Any ideas?

6. What is context switching?

7. Communication protocols.

8. OOP concepts.
