Interview process consisted of two technical rounds and one HR round. The first technical round was easy and mostly consisted basic questions of analog electronic circuits, OPAMPs, I2C, SPI and basic C questions. The second technical round was more difficult and consisted around 10 questions on Opamps, ADC, wheatstone bridges, C functions, pointers. The questions on opamp were difficult. An opamp circuit was given and I need to analyze it and identify the circuit or what would be the output. Easy ones included summing amplifiers, differential and integral amplifiers, and some others were mixed so it was a bit complex. They will ask lot of questions on projects from your previous company so be ready and thorough with your past projects. Finally, the HR round was salary negotiation. The entire process was very fast and was over in less than a week.

There was three rounds of interviews. One with HR two with the manager and three other senor engineers. Most of the questions were asked by the engineers. There was a interview with HR only. It was not technical but gave more information on the nature of the company, benefits and company culture.
