Started with telephonic round which discussed experience & some embedded knowledge on ARM, RTOS, C. Another telephonic with different person with similar theme. Was called for face to face to Bangalore office. Total 4 rounds (first telephonic guys, then separate discussion with two architects plus manager & finally group director). Ended with HR discussion. Overall interview was fine & not very deeply technical. Although role did not mention to have a background in security based on my discussion it seems they wished for it since the group works for automotive secure connectivity (which i did not have)
