Section#1
This is the aptitude section consisting of 45 questions to be attempted in 45 minutes. As is in all the exams, this section is based on the MBA pattern of examination.
Section#2
his is the technical section. There is a separate paper for hardware and software. Candidates have to mention beforehand whether they want to write the software or the hardware paper.This section also carries 45 questions to be completed in 45 minutes.
Interview

.Typical questions in C and Data Structures
1. WAP to interchange 2 variables without using the third one
2. Explain quick sort and merge sort algorithms amn derive the time-constraint relation for these.
3. Explain binary searching, fibonacci search
4. General questions on binary trees, transversals
5. General questions on graphs and their representation.
Typical Questions on Operating Systems
