First round : Video round with 5 standard questions. Second round : Technical telephonic for about 1 hour. C, basic programming, Math and Signal processing. All the questions were posted here already. Prepare everything mentioned here, do not leave even a single one. The interviewer doesn't say if your answer is right or wrong. They just move on to next question. I have answered 100% correct. But after 5 days, the online status got updated to "match not ideal this time" !!! So not sure what they are looking for.

There were three phases for recruiting procedures. The first stage was a brief and relaxing conversation, the second stage was about technical things and hiring manager asked several questions in the third stage.
