-Recruiter cold called after my resume was submitted for another position. -Applied to a DSP FW engineer position - 1st round - Technical + behavioral + resume based questions with Hiring Manager - Got positive feedback, but manager wants me to interview for a different position (virtual onsite interview) - Applied to the position, not exactly matching but there was some relevance - Onsite (6 rounds total including with recruiter) -1st round - General questions around embedded systems, resume based, Q format values. 1 coding - find number of 1's in a number - 2nd round - Technical questions around Wireless communications, FFT's, how to decide on FFT length for a certain sample rate. (Found it difficult as wireless is not what I prepared for) - 3rd round - Discussion around my resume, some questions and probing around embedded system design. Coding questions including - find size of structure which has variable specifying bit field, code a function to change endianness of a value - 4th round - With manager, again discussion on resume, technical aspects of the job (This was a light round in terms of technicality) - 5th round - Technical questions on Wireless communication, different modulation. One coding question to convert soft bits of qpsk to hard bits where size of soft bits is 6 bits in a continuous data stream. - Recruiter round was about why apple, why did you leave last job, why are you looking to switch now.
