Lengthly process which took around a month to finish. Total 4 rounds of interview including the initial phone screening. The recruited promised to finish the process within couple of weeks but ended up to do one more round of interview. Most of the questions in technical rounds was redundent , did not find a reason to do 1 more round of tech session. Answered all the question pretty well. They asked questions out of the position duties domain but I did not miss them to answer properly. Like they did not ask for C++ programming knowledge in the job postiong but asked FIFO and LIFO stack in C++ and embeded system experience. I even solved the programming challenge within 15 minutes correctly , but got a negative reply from HR in the next week.
