Interview Questionnaire 

9 Questions

  • Q1. Find the left view of a binary tree?
  • Ans. 

    The left view of a binary tree shows the nodes that are visible when the tree is viewed from the left side.

    • Traverse the tree recursively from left to right

    • Print the first node encountered at each level

    • Example: For tree with root node A, left view is A, B, D, G

  • Q2. What is the differnce between c and c++?
  • Ans. 

    C++ is an extension of C with object-oriented programming features.

    • C++ supports classes and objects while C does not.

    • C++ has better support for polymorphism and inheritance.

    • C++ has a standard template library (STL) for data structures and algorithms.

    • C++ allows function overloading while C does not.

    • C++ has exception handling while C does not.

  • Q3. FInd the middle of the linked list?
  • Ans. 

    To find the middle of a linked list, use two pointers - one moving at twice the speed of the other.

    • Use two pointers - slow and fast

    • Slow pointer moves one node at a time, fast pointer moves two nodes at a time

    • When fast pointer reaches the end, slow pointer will be at the middle

  • Q4. What are semaphores, differnce between them, Different OSI layers , deadlock protocols, ACID protocols in dbms
  • Ans. 

    Semaphores, OSI layers, deadlock and ACID protocols in DBMS

    • Semaphores are used for process synchronization and communication

    • OSI model has 7 layers: Physical, Data Link, Network, Transport, Session, Presentation, Application

    • Deadlock protocols prevent processes from entering a deadlock state

    • ACID protocols ensure database transactions are reliable and consistent

  • Answered by AI
  • Q5. Find the boundary traversal of a binary tree?
  • Ans. 

    Boundary traversal of a binary tree is the process of visiting the nodes on the boundary of the tree.

    • Start with the root node and traverse the left boundary nodes from top to bottom.

    • Traverse the leaf nodes from left to right.

    • Traverse the right boundary nodes from bottom to top.

    • Exclude the leaf nodes that are already traversed in the second step.

    • Repeat the above steps for all the subtrees of the binary tree.

  • Answered by AI
  • Q6. What is the differnce between linear and non linear data structure?
  • Ans. 

    Linear data structures have a sequential arrangement of elements while non-linear data structures have a hierarchical arrangement.

    • Linear data structures have a fixed number of elements and are easy to traverse.

    • Non-linear data structures have an arbitrary number of elements and are difficult to traverse.

    • Arrays, linked lists, and stacks are examples of linear data structures.

    • Trees, graphs, and heaps are examples of non-l

  • Q7. Steps associated with client server connnection request?
  • Ans. 

    Steps for client server connection request.

    • Client sends a connection request to the server.

    • Server receives the request and sends a response.

    • Client receives the response and establishes a connection.

    • Connection is maintained until terminated by either party.

  • Answered by AI
  • Q8. Producer and consumer problem?
  • Ans. 

    Producer and consumer problem is a synchronization problem in computer science where multiple processes share a common resource.

    • It occurs when multiple processes try to access a shared resource simultaneously.

    • The producer produces data and the consumer consumes it.

    • The problem is to ensure that the producer does not produce data when the buffer is full and the consumer does not consume data when the buffer is empty.

  • Answered by AI
  • Q9. Difference between process and threads?
  • Ans. 

    Processes are independent programs while threads are lightweight processes within a program.

    • Processes have their own memory space while threads share memory space.

    • Processes communicate through inter-process communication while threads communicate directly.

    • Processes are slower to create and terminate than threads.

    • Examples of processes are web browsers, word processors, etc. while examples of threads are spell checkers,

  • Q1. Why UDP and not TCP in project
  • Ans. 

    UDP is preferred over TCP in this project due to its low latency and lightweight nature.

    • UDP is a connectionless protocol, which means it does not establish a direct connection between the sender and receiver.

    • UDP is faster than TCP as it does not have the overhead of establishing and maintaining a connection.

    • UDP is suitable for applications where real-time data transmission is crucial, such as video streaming or online ...

  • Q2. How would you clear the 7th bit in a 32 bit register
  • Ans. 

    To clear the 7th bit in a 32-bit register, perform a bitwise AND operation with a mask that has all bits set to 1 except the 7th bit.

    • Create a mask with the 7th bit set to 0 and all other bits set to 1

    • Perform a bitwise AND operation between the register and the mask

    • Store the result back in the register

Interview Preparation Tips

Round: Test
Experience: Questions were based on C concepts, given piece of code, find error, output, etc then data structures, bit manipulation, a few aptitude questions were also there (around 5-7).
Tips: Practice aptitude, C, data structures (geeksforgeeks.org is a good source).
Duration: 1 hour
Total Questions: 30

Round: Technical + HR Interview
Experience: I was asked to explain project in detail, I had done projects on embedded, so was asked about that, details like what fields did you use in that structure, why this implementation and not some related other. Memory management, network communications, operating systems. Then questions on C concepts like memory allocation, function pointers, then data structures like linked lists, then bit manipulation in registers. Questions from electrical coursework. Then later, why higher studies, would you still go for higher studies if you had a good job at a company, why etc.
Tips: Be thorough with C (know your Kernighan & Ritchie) and be prepared to go into details about your projects.

Round: written test
Experience: it was elitmus test conducted by the company itself on campus. As per my knowledge only those scoring 90 percentile got selected for round 2.
Tips: Attempt only those ques that are necessary for scoring 90+ in e litmus. Specially in verbal don't attempt more then required questions, though you might be tempted. The aim is not to score max bt to score 90+

Round: Technical Interview
Experience: This was a programming based round. I was asked to write algorithms for various array linked list based problems. There was cross questioning prompting to reduce complexity and to use different data structures for same problems.

Mostly it focused on subjects like c, data structures and ADA.
Tips: Be clear with basic of data structures and algorithms. Pointers, queue, stacks, array linked lists, sorting etc are the keywords.

Round: Technical Interview
Experience: This was a information security specific round since that was my major. In depth cross questioning on my thesis topics, honeypots, network intrusion etc. Security certificates, and on the go problems to provide security solution layer wise in different scenarios. Security concept of torrents was also asked in detail.
Tips: It was more of a security discussion and throwing of ideas about how things in a particular case could work or could not. Don't worry about right or wrong answer just be clear with your reasoning about the solution you are suggesting.

Round: Other Interview
Experience: I don't know what to name this round, but it focused mainly on developing test cases for an object. Say they gave me a stapler and said to develop a test plan listing down test cases for a given object to pass so that it can be confirmed that it is a stapler. Another scenario was with a lift.
Tips: This is one round where your presence of mind and inter personal skills matter. I think the way you present your thoughts was most important here.

Round: Behavioural Interview
Experience: This was was mostly about how would you react in a given professional situation
Like your assigned work could not be completed on time, or if you are doing something wrong with the work assigned.
