Technical Interview Questions for IT Engineers in SSB

SSB (Sanctioned Selection Board) interviews are renowned for their unpredictability. Regardless of your specialization, you might find yourself answering a wide range of questions, from current affairs and general knowledge to technical concepts.

For IT engineers, the interview may challenge your understanding of various fundamental and advanced computing concepts. Whether you are a fresh graduate or a repeat applicant, this article provides a comprehensive overview of the typical technical questions you might encounter.

Understanding Basic Computing Components and Concepts

The interview board often expects candidates to have a solid grasp of fundamental computing components and operations. Here are some key questions:

Processor, Assembler, Compiler, Loader, and Linker: Explain the functions served by these components and how they interact. Hard Disk and Its Purpose: Describe the purpose and structure of the hard disk and discuss its role in data storage. Cache Memory: Explain the role and benefits of cache memory in computer architecture. Basics of the Operating System: Outline the primary functions of an operating system and its components. Software Development Phases: Differentiate between the design and implementation phases of software development. RAM vs. ROM: Compare the differences and usage scenarios for Random Access Memory and Read-Only Memory. DRAM (Dynamic RAM): Discuss the data storage mechanism in DRAM and how it functions. Paged Segmentation and Segment Paging: Compare and contrast these memory management methods. Compiler vs. Interpreter: Explain the differences between a compiler and an interpreter. Microprocessor vs. Microcontroller: Differentiate these two valuable components of computing devices. Real-Time Systems: Define real-time systems and discuss their importance and characteristics. Soft and Hard Real-Time Systems: Clarify the distinctions between soft and hard real-time systems. Mission Critical Systems: Explain what constitutes a mission-critical system and the factors contributing to its importance. Process Memory Sharing: Discuss what this process involves in distributed systems. Processor State During Waiting: Define the state of a processor when it is waiting for an event to occur. DOS Command : Which command in DOS is used to duplicate an entire diskette? Deadlock: Explain the concept of deadlock in computer science. Microkernel vs. Macrokernel: Highlight the differences and provide examples of microkernels. Bottom-Up vs. Top-Down Methodology: Describe the scenarios in which each methodology is applicable. Primary vs. Secondary Storage: Compare the differences between primary and secondary storage. Multi-tasking, Multi-programming, and Multi-threading: Outline the differences between these concepts and how they are applied in computing environments. Multi-threading vs. Multi-tasking: Discuss the distinctions between multi-threading and multi-tasking.
