4 rounds of Technical interviews followed by 1 HR round. Technical interview included questions on Analog electronics and Digital electronics. ADCs, DACs, RC filters, integrators, differentiators, op-amp circuits etc., Hardware board design concepts like components selection, and PCB Layout guidelines were asked. The internal circuitry of JK flip flop, NAND gate truth table, and communication interfaces like I2C, and SPI were questioned.

I’d like to share some observations about the current recruitment process. I received an email at around 12 a.m. (which is very unusual since it is beyond office hours) regarding a technical exam scheduled for 7 a.m. the same day. Unfortunately, the email did not include my name or the position I applied for, which made it feel impersonal and confusing. After taking the exam, I also received a text message that didn’t mention even the sender’s name, only stating it was from Analog Devices. Compared to past experiences with this company’s HR, the communication seems less professional now. I believe improving clarity, timing, and etiquette in candidate communication would make the recruitment process much more positive and effective.
