Arm interview questions

I applied through campus drive. There was an online test of 2.5 hours. 70 questions from technical and 30 from aptitude and data interpretation. Questions were from 8085, 8051 architecture, an assembly program. C program based questions were focused on pointers, operator precedence, and recursion. Memory related questions pretty basic and C++ questions of file handling and classes and objects. Basic data structure related questions. Aptitude questions were easy but data interpretation questions were a little lengthy. Don't answer the question if you don't know anything about that. Only answer if 50:50 chances to get the correct answer. Result declared after 3 days of the test and 10 students shortlisted out of 70 approx. Out of 10 students interviewed, 1 got an offer for an internship.

The process was good, HR was also very friendly and positive The technical interview experience was poor. Initial 2 interview round went very well and answered all C, Linux, Kernel, DS answers. In 3rd round of interview : Even though I have not written anything related to memory management work and its design in my CV, the interviewer has spent almost an hour on the same topic even after I have refused several times not to have much idea on that, It was just a time pass of an hour interview, also the questions were mostly on memory design. In 4th round immediately after 3rd one: C++ basic questions, that I had answered well, but the interviewer was expecting me to have advance knowledge on it(again I have wrote basic of c++ in my resume clearly). They might be asking based on their position requirement c++ & memory management related requirement but resume screening should have done properly if they had strick requirement instead of wasting 4-5hrs of time(telephonic + 4hrs interview).
