They asked about my project, OOPS, and embedded system-related questions, as I am pursuing a master's in embedded systems. All the questions ranged from basic to intermediate levels. They asked me to share my screen and type the outputs of some code snippets they provided on the CodeChef website.

Project:

• What is your contribution to the project?
• What difficulties did you face during the project, and how did you overcome them?

Oops:

• What is the output of the following program implementing compile-time polymorphism?
• Write a program demonstrating run-time polymorphism.
• Explain the virtual keyword.
• Explain pure virtual functions.

Embedded Questions:

• Binary semaphore and mutex
• Deadlock
• Priority inversion, inheritance, and ceiling
• SPI and I2C
• Interrupts and ISR
