basics of semiconductor(diode, mosfet,bjt devices), network theory(mainly RC circuits), opamp, basics of any programming language, basic of digital logic, also a different panel asked basics of RF signals, there written paper also contents some very basics of power and energy consume by different passive elements.

fundamental circuit intuition, problem-solving skills, and deep understanding of device physics rather than just rote memorization of equations. You will be expected to think out loud, draw waveforms, and analyze small-signal
