WRITTEN TEST:
The written paper is of one hour duration and consists 30 questions which are divided into three sections:
Aptitude Section - 15 questions in 20 minutes.
Technical Section - 25 questions in 20 minutes.
C Programming Section - 15 questions in 20 minutes.
In the technical section, questions from Microprocessors, Operating Systems, and Computer Networks etc. are asked. All questions are multiple-choice type.
INTERVIEW:
The interview as usual lays stress on your technical stream. Questions from C, C++, Operating Systems, and Computer Networks will be asked. The panel will also ask about your favorite subject. You should have a good grasp on the subject because you will be grilled on those subjects.

Rest of the paper is based on similar questions.
I don’t remember them completely but I'll just give a basic idea about them below
* 5 programs are scheduled from Monday to Saturday, Monday is not holiday, and PQRST is the programs. The day before P is holiday, and some other clues are given, we have to find the sequence (4 questions)
* Suppose U R the prisoner, there are two guards who will tell truth or one will tell truth. There is a gate for liberty and another foe hell. Asking about which sequencing is sufficient to find the gate for liberty??
Some questions are given, like
i. Are U told truth?
ii. Another tells truth or not??
iii. Both of U R telling truth??
iv. Both of U lieing??
v. --------------
* There are WIFE and HUSBAND at one side of river. They have one child; they want to cross the river. The child can't be lonely. The boat boy won't permit more than one to cross the river, what is the correct way to cross the river??
* There are 7 targets, A B and C has to shoot them. All should be shot down consecutively.
1. The number of chances for A and B are not less then 2,
2. C has only one chance
3. A can't shot 3 times consecutively.
4. B is permitted to shoot in even chances only.
They have given some 2 or 3 MCQ questions on this.
