Aptitude is just general Math. programming questions were slightly tricky. Mostly all the questions were of the format finding the output or finding the error in the code.
Tips: As i said earlier, prepare popular logical reasoning questions and try to find out some good coding rules (like difference between i++ and ++i )
Duration: 60 minutes
Total Questions: 60

Round: Technical Interview
Experience: All the questions were related to Computer Networks, Data Structures and your Resume.  Some puzzles were also asked

  • Q7. What is page fault
  • Ans. 

    Page fault is an error that occurs when a program tries to access a page that is not currently in physical memory.

    • Occurs when a program tries to access a page not in physical memory

    • Operating system retrieves the page from disk to physical memory

    • Can cause performance issues if it happens frequently

    • Can be caused by insufficient memory or memory fragmentation

  • Answered by AI
  • Q8. How does a page fault is serviced
  • Ans. 

    Page fault is serviced by fetching the required page from disk to memory.

    • When a process tries to access a page that is not in memory, a page fault occurs.

    • The operating system then checks if the page is present in the disk.

    • If the page is not present in the disk, it results in a segmentation fault.

    • If the page is present in the disk, it is fetched to memory and the process continues.

    • The process is then restarted from the

  • Ans. 

    Calculating round trip time and bandwidth of network using Pin

    • Use Pin to measure the time it takes for a packet to travel from source to destination and back

    • Divide the round trip time by 2 to get the one-way latency

    • Calculate bandwidth by dividing the size of the packet by the one-way latency

    • Repeat the process with different packet sizes to get an average bandwidth

    • Use Pin's built-in tools to analyze the data and generat

  • Answered by AI
  • Q11. Can you measure congestion in the system using Ping and how?
  • Ans. 

    Yes, Ping can be used to measure congestion in the system.

    • Ping measures the round-trip time for packets to travel from the source to the destination.

    • If the round-trip time is high, it indicates congestion in the network.
