The written test can be aced with practice.

Aptitude consists of 20 questions (10 were data interpretation, and the rest were quant questions).

Coding requires good experience in C and Data Structures.

Core topics covered:

• Digital (7 questions)
• Oscillators (3 questions)
• Microcontroller (3 questions)
• Basic analog electronics like BJTs and diodes (3 questions)

The interview lasted around 45 minutes. It will be easy if you have a good command of the projects you have done. Questions will be decided based on your answers.

Describe the oscillator principle. Describe the PLL. Describe CMOS circuits. Provide the Verilog code for SRAM. Explain the difference between a latch and a flip-flop. Distinguish between sequential and combinational circuits. Describe the Wein bridge oscillator. Compare NAND vs. NOR gates and explain which is "best" and why. Scale yourself 0-10 in Python. Describe the biggest challenge you have faced. What do you know about this company? What would you like to know about this company?
