10+ GMR Group Interview Questions and Answers
Q1. 18. How to find how much process are running on server
Use command line tools like 'ps' or 'top' to find the number of running processes on a server.
Use 'ps aux' command to list all running processes and count the number of lines
Use 'top' command and look for the 'Tasks' section which shows the number of running processes
Use 'htop' command which provides a more interactive and detailed view of running processes
Q2. 19. For taking Wireshark logs which command we use
The command used for taking Wireshark logs is 'tcpdump'.
Wireshark is a network protocol analyzer tool
Tcpdump is a command-line tool used to capture network traffic
Tcpdump can be used to capture packets and save them as a file for analysis in Wireshark
Example command: tcpdump -i eth0 -w capture.pcap
Q3. 6. Which bandwidth are you using with RB's
RB's bandwidth usage depends on the specific product and its features.
RB's have different bandwidth usage depending on the product
The bandwidth usage also depends on the features of the product
Examples of RB's with different bandwidth usage are RB750Gr3 and RB4011iGS+RM
Q4. 5. Which numerology are you using
I am not using any numerology in my work as a Senior Software Engineer.
I do not believe in numerology and do not use it in my work.
My focus is on writing efficient and effective code.
Numerology has no place in software engineering.
Q5. A variation of number of connected islands from graph
Count the number of connected islands in a graph
Use Depth First Search (DFS) or Breadth First Search (BFS) to traverse the graph and mark visited nodes
Keep track of the number of islands encountered during traversal
An island is a group of connected 1s in a 2D grid, where '1' represents land and '0' represents water
Q6. Thread synchronisation, print alternate numbers using 5 different threads
Use 5 threads to print alternate numbers with thread synchronization
Create 5 threads, each responsible for printing a specific set of numbers
Use mutex or semaphore to synchronize the threads
Thread 1 prints odd numbers, Thread 2 prints even numbers, and so on
Ensure proper handling of thread creation and synchronization
Example: Thread 1 prints 1, 3, 5, ... Thread 2 prints 2, 4, 6, ...
Q7. 13. Find loop in linked list
To find a loop in a linked list, use Floyd's cycle-finding algorithm.
Use two pointers, one moving at a rate of one node per iteration and the other moving at a rate of two nodes per iteration.
If there is a loop, the two pointers will eventually meet at the same node.
If there is no loop, the faster pointer will reach the end of the list.
Time complexity: O(n), Space complexity: O(1)
Q8. 16 .what is semaphore
Semaphore is a synchronization object used to control access to a shared resource.
Semaphore is a signaling mechanism used to control access to a shared resource
It maintains a count of available resources and blocks the thread if the count is zero
Semaphore can be used to implement critical sections, mutexes, and barriers
Examples include controlling access to a database or limiting the number of concurrent connections
Q9. 1. Bwp part concept
BWP part concept refers to the concept of breaking down a software system into smaller, more manageable parts.
BWP stands for Break-When-Problematic
It helps in identifying and isolating issues in the system
Each part should have a clear responsibility and interface with other parts
Q10. 12. What is cce
CCE stands for Continuous and Comprehensive Evaluation.
CCE is a system of evaluation in education that assesses students' progress continuously throughout the year.
It is a comprehensive approach that takes into account various aspects of a student's development, including academic, social, and emotional.
CCE aims to reduce the emphasis on rote learning and promote a more holistic approach to education.
It was introduced in India as part of the Right to Education Act in 2009.

Q11. 14 . WAP set bit or reset bit
WAP set bit or reset bit is a programming concept used to manipulate individual bits in a binary number.
Setting a bit involves changing its value from 0 to 1.
Resetting a bit involves changing its value from 1 to 0.
This concept is commonly used in low-level programming and hardware manipulation.
Example: Setting the 3rd bit of a binary number 1010 would result in 1110.
Example: Resetting the 2nd bit of a binary number 1101 would result in 1001.
Q12. 2. What is corset
Corset is a tight-fitting undergarment worn to shape and support the torso.
Corsets were popular in the Victorian era.
They were worn by women to achieve an hourglass figure.
Modern corsets are often used as fashion statements or for waist training.
Corsets can be made of various materials such as satin, leather, or lace.
They can be fastened with laces, hooks, or zippers.
Q13. 4. Ue attach procedure
UE attach procedure is a process in LTE network where a UE establishes a connection with the network.
UE sends RRC Connection Request message to eNodeB
eNodeB sends RRC Connection Setup message to UE
UE sends RRC Connection Setup Complete message to eNodeB
eNodeB sends RRC Connection Reconfiguration message to UE
UE sends RRC Connection Reconfiguration Complete message to eNodeB
UE is now attached to the network
Q14. 17. Array vs linkedlist
Arrays are faster for random access, while linked lists are better for frequent insertions and deletions.
Arrays have a fixed size, while linked lists can grow dynamically.
Arrays are stored in contiguous memory, while linked lists use pointers to connect nodes.
Accessing an element in an array is O(1), while in a linked list it is O(n).
Inserting or deleting an element in an array is O(n), while in a linked list it is O(1) if you have a reference to the node.
Arrays are better fo...read more
Q15. 3. Rach procedure
Rach procedure is a surgical procedure used to correct scoliosis.
Rach procedure involves placing screws and rods in the spine to straighten it.
It is typically used for patients with severe scoliosis.
The procedure can take several hours and requires a hospital stay.
Physical therapy is often necessary after the procedure to aid in recovery.
