– Test Cases for Above program
Note:
1) During all the three interview they were noting down each and every statement told by u in the laptop… they were noting down how r u approaching the question…
2) In microsoft interview , the code written shud be correct in one shot. No logical errors..

Kritikal
Basically they were looking for Vision ppl.. and since i hadn’t done any project in vision ..so they said that they don’t hav requirement in non-vision.
In the interview they basically asked some OS stuff related to Semaphores.
Result: Not Selected

HR Interview..

BroadCom
Tech Interview-1
No of ppl-2
They were basically focussed on embedded systems.. so they were asking more from OS related stuff….

– Variation of Bounded Buffer Problem/Reader’ Writers Problem in term of Hardware…
– Interrupt driven IO
– Programmable IO
– Memory Mapped IO
– CPU Scheduling
– Link list insertion
– Some details of Malloc,calloc
This interview was basically checking how are u approaching new problems using OS concepts
Tech Interview- 2
– Function swapping two pointers which is pointing to 2 integers (not swapping values)…
– Little Endian/Big Endian representaion
– Change the intger from Little endian to big endian
– Priority Inversion
– Some Details about Context switching
– PC(Program Counter) , IR(Instruction register)
HR

Result :Selected
Total No of Person In the interview : 11
Total No of Person In the Selected : 1

Moral of the Story:
1) The Most important advice is to build ur analytical/aptitude skills strong.. becoz even if u r technically strong .. and if ur aptitude solving speed/accuracy is low then u can’t reach interview level.
2) Most Important subject are Algorithms,OS,C/C++. Study OS in depth… try to co-relate the concept of Programming language(C/C++) , Compilers and OS with each other… So that each and every answer of “Why” can be answered..
e.g. — 1) Where Static variables are stored
2) Where Static Functions are stored
3) Memory management in C
4) Memory management in C++/Java
5) How stacks are build during runtime of programs
6) Linking and Loading of C-Programs By Compilers and later how its loaded to execute
7) Where Shared Objects/DLLs are kept for a process in run time.
8) Some concepts relating CO(Computer Organisation) and OS
etc…
3) Databases are secondary stuff..

Hope these stuff are clarifying some of doubts…
