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 There are two rounds of interviews, viz., the technical and and the HR round Technical and Personal Round for Software Candidates Mainly subjective questions in C, Operating Systems,DBMs, Data Structures are asked interspersed with some on the candidate's personal background. .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 1. Demand paging, page faults, replacement algos, thrashing, etc 2. Paged segmentation and segment paging In this section, case studies are presented are presented before the candidate to percieve his reaction and his/her communication skills are tested. IBM expects teamwork and teamspirit from the candidates and their answers should reflect this attitude Typical question is You are a project manager of a big multinational project. There is a person X, assigned to you who has the best technical skills required for the project, even better than you.
