Arm interview questions

Applied online and I was contacted by a recruiter for availability. A phone screen (after 2 days from the email), and then an onsite (After a week) and heard about the status after a month from the onsite interview. Interview is tough and have to know fundamentals good enough to crack it. All white boarding for all the 7 interviews on the same day except during lunch interview. Interviewers were well prepared and very friendly. Overall, after the interview I left with a good experience.

I am yet awaiting a response from them after telephonic interview. But I will still post the details of telephonic interview that happened! I was contacted by a consulting firm which was recruiting for ARM (read recruiting as head hunting). I applied and my interview was scheduled I was interviewed by 2 Staff Engineers at ARM. The telephonic interview was for only 1 hour. As long as you are willing to work out the interviewers would help you derive at the answers. Here are the questions which were asked during interview for me 1. Details of my job. Questions on my current role at my current company 2. On any microcontroller before the program hits main() what all is done ? 3. Where will the global variable int i reside in a micro controller and where all it will go when the program executes ? 4. What is a SCL ? What does it do. Does the partition happen during compilation or execution 5. Caches (This is something I am really scared and un-aware of) They asked the following questions ---> a) When are caches used ? b) When is it necessary to do a cache management? c) Suppose you write a C program to access an a large array and you are replacing some 10 random numbers in that array, Do you need to take care of cache handling there ? Since I was totally lost on cache, they did explain me how the cache is needed and stuff. After this the interview ended! So I am assuming that it won't go further. I had prepared all C programs, ARM architecture, but was stuck cos of the Caches ! :-(
