Round 1: Storage classes in C, etc. Basic RTOS questions like priority inversion, semaphore and mutexes, exceptions, Embedded question on I2C, SPI, RS485, PWM, TCP/IP layers, transmission control Second round: started on negative note that we are not like other companies to give you this-that and all, your profile doesn't suit the requirements etc. Asked few RTOS related questions like which RTOS you have used? Asked me to write a c program and then read it out (since it was through VC) lol...
