- Q1. Explain what is OOPs
- Ans.
OOPs stands for Object-Oriented Programming, a programming paradigm based on the concept of objects.
OOPs focuses on creating objects that contain data and methods to manipulate that data.
Encapsulation, inheritance, and polymorphism are key principles of OOPs.
Examples of OOPs languages include Java, C++, and Python.
- Q2. Data structures in C++
- Ans.
Data structures in C++ are used to store and organize data efficiently.
Data structures like arrays, linked lists, stacks, queues, trees, and graphs are commonly used in C++ programming.
Arrays are used to store a collection of elements of the same data type.
Linked lists are used to store elements in a linear order.
Stacks follow the Last In First Out (LIFO) principle.
Queues follow the First In First Out (FIFO) principle.

The water-cement ratio affects the amount of cement needed; lower ratios require more cement.
Example: A typical mix for structural applications might be 1:2:4 (cement:sand:aggreg...
- Q2. 1sqm2 plaster use cement kg
- Ans.
The amount of cement needed for plastering 1 sqm varies based on mix ratio and thickness.
Standard plaster mix ratio is 1:4 (cement:sand).
For 1 sqm at 12mm thickness, approximately 8-10 kg of cement is needed.
Higher thickness or different mix ratios will increase cement requirement.
Example: For a 1:6 mix, you may need around 6-8 kg of cement per sqm.

Interview Preparation Tips
Experience: I consulted my seniors for preparation of my resume. I believe that seniors provide the best possible insights in this regards. I had a standard resume for all the companies.
Round: Test
Experience: I had prepared for the CAT examination which helped me in these written tests. The first round was the written test. The criterion for the written test was to have a CGPA more than 6.0. There was an aptitude test and a technical test. The technical test consisted of programming questions based on C++ and data structures. From data structures they asked a lot questions based on tree traversals and from C++. A large number of questions from pointers and arrays were also asked.
The aptitude test was slightly easier than the CAT examination standards. Majority of the questions were related to data interpretation and some were of based on logical reasoning. The total duration of the both the tests combined was 90 minutes.
Around 50 people appeared for the first round and nearly 13 got shortlisted for the next round.
Tips: For the written tests, particularly the aptitude section, if would really help if you have prepared for the CAT examination. There is a book written by an author named R.S. Agarwal which would prove to be beneficial from the point of view of these written tests.
Duration: 90 minutes
Round: Group Discussion
Experience: I did not prepare much for the GD’s. However I did keep myself abreast with certain latest happenings.There were no group activities conducted in the recruitment process of Century Link.
Round: HR Interview
Experience: For HR interviews I prepared answers to some frequently asked HR questions. I found these questions on the internet. Generally the questions asked in the interviews are related to the profile on offer; for instance in A2Z interview I was asked a lot of questions from power systems since it was a core company and in Century Links I was asked questions from C++ and data structures since they had come to recruit for a software engineering profile.
Round: Technical Interview
Experience: In this interview I was questioned on my C++ and data structure knowledge. They asked me questions on pointers and further asked me to explain the concept of dangling pointers. They did not want me to write down the complete code with proper syntax's of the problems asked to me. They only asked me to write the algorithms of the various problems.
They also asked me some puzzles. Unfortunately, I was not able to solve any of them. During the course of the interview they asked me to specify the reason for my keen interest in joining an IT company.
At the end of first interview some candidates were shortlisted and called for the second round of interview.
Round: Technical Interview
Experience: The second interview was conducted by a senior company official. He enquired about my project and again, like in the first interview, asked me to state the reason for my interest in joining an IT company.This interview round was an elimination round.
Round: HR Interview
Experience: The interview was an HR interview. Candidates who reached till this interview were all selected; basically this interview was like a formality to check the candidate’s fit with the company.
College Name: IIT ROORKEE
Motivation: I had never heard of the company before the recruitment season. I attended the PPT organised by the company, I found the company to be a well reputed/established company and thus applied to it. The profile was open for Electrical, Computer Science, Mechanical and Electronics engineering students.
I appeared for an interview before Jan 2016.

- Q1. What are Little Endian and Big Endian in the context of computer architecture?
- Ans.
Little Endian and Big Endian refer to the order in which bytes are stored in computer memory.
Little Endian stores the least significant byte first, while Big Endian stores the most significant byte first.
Little Endian is commonly used in x86 architecture, while Big Endian is used in architectures like SPARC and PowerPC.
Endianness can affect data transmission between systems with different byte orders.
- Q2. Write a program to determine if your system is little-endian or big-endian.
- Ans.
Program to determine system's endianness
Check the endianness by storing a multi-byte integer and checking the byte order
Use bitwise operations to extract the least significant byte
If the least significant byte is at the lowest memory address, it's little-endian
If the least significant byte is at the highest memory address, it's big-endian
- Q3. What is the volatile keyword in programming?
- Ans.
The volatile keyword in programming is used to indicate that a variable's value can be changed unexpectedly.
Volatile keyword is used in multithreaded programming to prevent compiler optimizations on variables that can be changed by other threads.
It tells the compiler not to cache the variable's value in a register, ensuring that every access is made to the variable's memory location.
Commonly used in embedded systems pr...
- Q4. What is the use of a function pointer in C?
- Ans.
Function pointers in C are used to store the address of functions, allowing for dynamic function calls and callbacks.
Function pointers can be used to implement callbacks in event-driven programming.
They can be used to switch between different functions at runtime.
Function pointers are commonly used in implementing data structures like function pointers in an array of function pointers.
Example: void (*funcPtr)(int) = &a...
- Q5. Design a data structure to implement multi-threading.
- Ans.
Design a data structure for multi-threading
Use a thread-safe queue to manage tasks for each thread
Implement a lock or semaphore to control access to shared resources
Consider using condition variables for synchronization
Use atomic operations for shared variables to prevent race conditions
- Q6. What does a kernel do?
- Ans.
The kernel is the core component of an operating system that manages system resources and provides a bridge between software and hardware.
Manages system resources such as CPU, memory, and I/O devices
Provides a bridge between software applications and hardware components
Handles tasks such as process scheduling, memory management, and device drivers
Controls communication between hardware and software layers
- Q7. What is a storage class in programming?
- Ans.
A storage class in programming defines the scope and lifetime of variables.
Storage classes include auto, register, static, and extern.
Auto variables are created when a function is called and destroyed when the function ends.
Register variables are stored in CPU registers for faster access.
Static variables retain their value between function calls.
Extern variables are declared outside of any function and can be accessed ...
