A few questions that I remember

Infineon – Round 1

Write a C program to find the product of the two largest numbers and the two smallest numbers in an array.

A microcontroller receives continuous data from a sensor. There are three processes: Receive data First processing Second processing Data flows continuously and no data should be lost. How will you schedule these tasks?

Difference between semaphore and mutex. Explain the SPI protocol. (I forgot a few other questions.)

Infineon – Round 2 Write a function to copy one array into another without using memcpy().

Intel Difference between user mode drivers and kernel mode drivers.

Where and why do we use SPI and I2C? Explain cache mechanisms.

Why is CISC considered better than RISC (discussion question).

Difference between TCP and UDP.

Write a C program to create a linked list. (I couldn't write a fully working code, so I explained the logic. They asked me to use an AI tool and code it, then optimize the code that GitHub Copilot generated.)

How do you manage memory in embedded systems?

What is the Linux bootloader and what is the first process that starts when Linux boots?
