Part 1: Aptitude (25 questions)
Its mainly consist of two sections:
1.Data Interpretation (20 questions) -  need to be fast in approach.
2.Basic level Numeracy (5 questions)

Part 2: Logical Reasoning

All 20 questions are on logical reasoning.  But u need to be really fast, or else u will end up marking wrong choices due to lack of time.

11.,12.there are 2 questions are based on pointer to string similar to test ur c skill type
13,14 . 2 questions are from c++
In which one is based on empty class
And in another question a structure(contains self-referential structure pointer) was declared inside a class and a object of that type of class was declared. something like
Class ABC{
Struct node{
Int a;
Struct node *ptr;};
}
ABC t;
What is sizeof(t) and sizeof(ABC)??
15. if(a=0)
Printf(“a is zero”);
Else
Printf(“a is not zero”);
16.No of node in full binary tree
a).13 b).15 c).16 d).14
17. a question based on heap tree property
18. a recursive function stores in-------
19. a question based on binary tree
20. Question based on file system
21. Question based on interrupt handing
22.Question based on bootstrap program
 

Third Round(Technical Interview) 45 Minutes


Questions were asked based on C java, operating systems, mathematical puzzles and from area of interest. The main emphasis was on c and java(core).

HR round was quite simple. 10-15 Minutes

Tell me about yourself.

Strengths, weakness
