  • Q14. From an incoming stream of numbers, construct a binary tree such that it is almost balanced
  • Ans. 

    To construct an almost balanced binary tree from an incoming stream of numbers.

    • Use a self-balancing binary search tree like AVL or Red-Black tree.

    • Insert the numbers from the stream into the tree.

    • Perform rotations or rebalancing operations as necessary to maintain balance.

    • Consider using a priority queue to handle the incoming stream efficiently.

  • Q16. What is a semaphore?
  • Ans. 

    A semaphore is a synchronization object that controls access to a shared resource through the use of a counter.

    • Semaphores can be used to limit the number of threads accessing a resource simultaneously.

    • They can be used to solve the critical section problem in concurrent programming.

    • Semaphores can have two types: counting semaphores and binary semaphores.

    • Counting semaphores allow a specified number of threads to access a...

  • Q17. Code the P and V operations of a semaphore
  • Ans. 

    The P and V operations are used to control access to a shared resource using a semaphore.

    • P operation (wait operation) decreases the value of the semaphore by 1, blocking if the value is already 0.

    • V operation (signal operation) increases the value of the semaphore by 1, releasing a waiting process if any.

    • P and V operations are typically used in synchronization mechanisms to prevent race conditions and ensure mutual excl...

  • Q18. Explain REST web service
  • Ans. 

    REST web service is an architectural style for designing networked applications that use HTTP as the communication protocol.

    • REST stands for Representational State Transfer

    • It is based on a client-server model

    • It uses standard HTTP methods like GET, POST, PUT, DELETE

    • Resources are identified by URIs

    • Responses are typically in JSON or XML format

  • Answered by AI
  • Q19. Is HTTP a stateless or stateful protocol?
  • Ans. 

    HTTP is a stateless protocol.

    • HTTP is stateless because it does not retain any information about previous requests or responses.

    • Each request is treated as an independent transaction, and the server does not maintain any knowledge of the client's state.

    • To maintain state, cookies or session management techniques can be used.

    • Statelessness allows for scalability and simplicity in web applications.

  • Q20. What is shared memory?
  • Ans. 

    Shared memory is a memory space that can be accessed by multiple processes or threads simultaneously.

    • Shared memory allows processes or threads to communicate and share data efficiently.

    • It is typically used in inter-process communication (IPC) to avoid the overhead of copying data between processes.

    • Shared memory can be implemented using operating system mechanisms like memory-mapped files or system calls.

  • Q21. What motivates me in life?
  • Q22. Explain the alignment issues in structures
  • Ans. 

    Alignment issues in structures occur due to memory padding and alignment requirements.

    • Structures may have unused memory space due to alignment requirements.

    • Padding is added to align structure members on memory boundaries.

    • Alignment issues can lead to wasted memory and decreased performance.

    • Compiler directives like #pragma pack can be used to control alignment.

    • Example: struct MyStruct { char a; int b; char c; };

  • Q24. Explain memory management unit
  • Ans. 

    Memory Management Unit (MMU) is a hardware component that manages memory access and translation between virtual and physical addresses.

    • MMU is responsible for translating virtual addresses used by programs into physical addresses in the computer's memory.

    • It provides memory protection by assigning access permissions to different memory regions.

    • MMU also handles memory allocation and deallocation, ensuring efficient use of...

    A socket is an endpoint for communication between two machines over a network.

    • A socket is a software abstraction that allows programs to send and receive data over a network.

    • It provides a mechanism for inter-process communication between applications running on different machines.

    • Sockets can be used for various network protocols such as TCP/IP, UDP, etc.

    • They are identified by an IP address and a port number.

  • Q26. I was asked in detail the concept of type casting in C
  • Q27. Can I declare a structure called ‘a’ which contains a structure called ‘b’ and ‘b’ in turn contains ‘a’?
  • Ans. 

    Yes, it is possible to declare a structure 'a' that contains a structure 'b' and 'b' in turn contains 'a'.

    • To achieve this, we can use forward declaration of one of the structures.

    • By using a pointer or reference to the other structure inside the first structure, we can avoid recursive definition.

    • This allows us to create a nested structure hierarchy.

  • Answered by AI
  • Q28. How do I find the offset of a member of a structure object? How would I do the same if I am not allowed to create the object at all?
  • Ans. 

    To find the offset of a member of a structure object, use the 'offsetof' macro. If not allowed to create the object, use 'sizeof' and pointer arithmetic.

    • Use the 'offsetof' macro to find the offset of a member within a structure object

    • If not allowed to create the object, use 'sizeof' to get the size of the structure and perform pointer arithmetic

I was interviewed in Dec 2016.

Interview Preparation Tips

Round: Technical Interview
Experience: On-site interview (5 hours).

4 back-to-back 45-minute coding interviews, followed by a design interview, with a lunch break with a Googler in the middle.

The first coding interview was a set of (surprisingly) trivial (no algorithms needed) incremental coding questions.

The two next coding interviews were problems straight from the "Cracking the coding interview" book. Even though I divulged that I'd solved pretty much exactly the same problem before, they didn't give me an alternative problem and I quickly coded up a general and optimal solution for the problems. Follow-up in-depth questions were minimal and not hard.

The last coding question was a pure algorithm question related to search trees/tries. No coding required, spent the whole time reasoning about the most effective algorithm. This was a bit of a brain twister.

The design question was related to high-level system design (not OO design) for storage and search in geographic data. Focus was effective search as well as scalability both in traffic and data volumes.

Tips: Read "Cracking the coding interview" or other similar literature. Solve all the problems and you should be good to go. If you solve a bunch of problems at HackerRank (or similar) as well, you'll have the added bonus of training on how to generalize the algorithms.

Interview Preparation Tips

Round: Test
Experience: Oracle consisted of an initial aptitude test followed by two rounds of technical interviews, one managerial interview and a final HR round. The company utilised the intermediary rounds as the elimination rounds.
In oracle, 3 M.Tech students and one B.Tech student(that's me) were chosen.

General Tips: Be extremely well prepared for any company. Research about the company's profile extensively before the company's interview. HR panel always looks for candidates who are well aware of the company in order to measure the candidate's interest. Data structures are absolutely necessary for any company. Improve coding skills through frequent participation in competitive programming arena such as codeForces, codeChef, HackerEarth etc. "Software development job profile was offered to me.
Unnecessary and irrelevant questions are to be avoided. We should raise questions only if we have some genuine questions. However any question related to job profile or location preference could be raised. "
"It was very grueling and tiring at first but the sweet taste of placement makes it all worth it.
Placements are a turning point in everybody's career."
Skill Tips: For oracle, a lot of research into company needs to be made. Operating systems and databases require more amount of preparation and priority in Oracle.
For data structures, online materials are excellent and in case of OOPS concepts, stronghold in either C++ or java programming language is necessary.
