Recently this company visited our campus for software developer profile
Round 1:
It was a online test.It consists of 3 sections- aptitude ,MCQ of C, C++, OS, DBMS, Networking and few of Java. These 2 sections were of 15 min each.The third section consists of 2 code.
After this round 16 people were shortlisted.
Round 2:(f2f Tech. round)
The interviewer asked me following questions-
- Description of my DBMS project.They asked,how tables are related, linking between them, the necessity of tables in the project. SQL Queries on the project. SQL joins.Types of Joins.
- What is the reason of having Multiple table in databases,why not a huge single table?
- DBMS transaction, ACID property.
- DBMS DEADLOCKS.
- Indexing in DBMS.Why Indexing?
- Why C++ is considered to advance then c language.
- What is Structured Programming?
- Discussion on Virtual function, Pure Virtual Function and Abstract Classes.
- Can Abstract class be FINAL in c++. (ans:NO). What’s the reason.
- Write a code for: Given Input: array1={1,7,3,2} Output: array2={42,6,14,21} without using division operator and efficient one.
- What is hashing?
- Write a code- Find 2 no’s in array whose sum is equal to a given no. then modified it for find a subarray in array whose sum is equal to a given no. in O(n) time complexity.
- They asked about my c++ project.They asked either it was done under any summer internship or it is a real-time project made for any industry? I said i made this during my semester under the guidance of faculty so they didn’t ask much about it.
- Explain Inheritance.
- Diamond problem in c++.
- What is Thrashing? How it is done? (while explaining the ans. they asked many related concepts of Memory management and virtual memory)
- what is Page Replacement? How to choose which page is going to be replaced?
Do you have any Questions?
I asked 3 questions 😀
ROUND 3:(f2f Tech. round)
They asked me about the subjects which were asked to me in my previous round. The interviewer asked me the following questions-
- Do you know Java? I said i m not comfortable in java.Then they said me to convince them to switch to c++ from java.
- It was hard to do so because java is advance language then c++ consisting a huge set of advantages over c++.
- Why is java platform independent? And how it is platform independent? And Why not c++ is platform independent?
- C++ copy constructor?
- Do Virtual Constructor exist?why or why not??
- What is Virtual Destructor and why? Explain Free and Delete. Difference Between them? Assignment operator in classes.(default and Userdedfined)
- Shallow copy Deep copy.
- How is runtime polymorphism done? explain compiler step to step process?
- Abstract Classes.
Code-
- Find mid, reverse a link list and one other link list code which i don’t remember.
- What is singleton classes.Write a code for it.
- Given a huge database : Design a data structure for it in most efficient way with optimized result of operations.
- Do u have any Questions?
