Round 1 was mainly focused on data structures and algorithms ,core java concepts and dbms
The minimum number of characters needed to convert a string into a palindrome is the length of the string minus the length of the longest palindromic subsequence of the string.
Find the longest palindromic subsequence of the given string.
Subtract the length of the longest palindromic subsequence from the length of the original string to get the minimum number of characters needed to convert it into a palindrome.
Round duration - 40 to 50 min

Tip 1 : Make you Data Structure and algorithms , Problem solving strong ( use to do some dsa problems on code studio and leetcode daily.
Tip 2 : Practiced Quality questions and mostly asked questions list available on codestudio( used company tags and topic tags) as quality matters more than quantity of questions .
Tip 3 : Give mock interviews, this really helped me as it gives you clearity and builds confidence.
Tip 4 : Read respective company’s interview experiences available on codestudio and other websites before going to actual interview, as this gives you idea about level of interviews and you can prepare beforehand.
Tip 5 : after solving dsa problem .Try to look in discussion section too as you can get more optimised or more efficient approach used by others to solve the problem.
Tip 6 : Prepare important concepts from Operating system,DBMS,System design too as that might also be asked.
Tip 7 : Do atleast 2 quality projects.
Not a Tip But : Lot of quality content available online, whenever felt like stuck with some concepts take help from senior or colleagues ( I use to watch coding ninja shorts by parikh jain whenever felt demotivated or stuck with concepts)
Tip 1 : Have a concise resume , don't fill your resume with unnecessary details like your address, relationship status etc.
Tip 2 :Resume should not be more than 2 pages( try to make it very concise in 1 page)

In this round, Interviewer tried to judge if my basics are clear or not.
He focused majorly on CS fundamentals.
He was pretty cooperative and gave me time after asking questions.
Yes, I have solved a complex Java problem on my own.
I once had to optimize a large-scale Java application by implementing multithreading to improve performance.
I successfully debugged a memory leak issue in a Java program by analyzing heap dumps and identifying the root cause.
I designed and implemented a custom data structure in Java to efficiently solve a specific problem.
Given an integer ‘N’, your task is to find and return the N’th Fibonacci number using matrix exponentiation.
Since the answer can be very large, return the answer ...
The task is to find the Nth Fibonacci number using matrix exponentiation and return the answer modulo 10^9 + 7.
Implement a function to find the Nth Fibonacci number using matrix exponentiation.
Return the answer modulo 10^9 + 7 to handle large values.
Use the formula F(n) = F(n-1) + F(n-2) with initial values F(1) = F(2) = 1.
Optimize the solution to achieve better than O(N) time complexity.
Consider solving the problem us...
Given an array ARR
of size N
, perform the operation to swap the Kth element from the beginning with the Kth element from the end of the array.
N = 5, K = 2
...
Swap Kth elements in an array with given constraints.
Create a function that takes the array, K value, and size of the array as input
Swap the Kth element from the beginning with the Kth element from the end
Handle edge cases like K being out of bounds or array size being less than 2

It was in late evening, interviewer was quite cool and asked me quite basic things about myself.
As the Government ramps up vaccination drives to combat the second wave of Covid-19, you are tasked with helping plan an effective vaccination schedule. Your goal is...
Given constraints and rules, maximize vaccines administered on a specific day during a vaccination drive.
Iterate through each test case and calculate the maximum number of vaccines administered on the specified day.
Distribute the available vaccines evenly across the days while adhering to the rules.
Ensure that the sum of vaccines administered does not exceed the maximum allowed.
Maximize the vaccines administered on the
Tip 1 : Know your project from the core.
Tip 2 : Make your basics of CS fundamentals crystal clear.
Tip 3 : Do all must ask Dsa questions, try to achieve the goal of 5-10 questions everyday.
Tip 1 : Add your github and other problem solving sites like leetcode and codeforces on your resume. It leaves a good impact.
Tip 2 : Brief your role on the projects.
Tip 3 : Mention your achievements and skills. Again they leave a good impact.
I applied via Approached by Company and was interviewed before Jun 2022. There was 1 interview round.
VRRP (Virtual Router Redundancy Protocol) and HARP (High Availability Redundancy Protocol) are protocols used for providing redundancy in network routing.
VRRP is used to provide a virtual IP address that multiple routers can share, ensuring high availability in case of router failure.
HARP is a proprietary protocol developed by Cisco that also provides redundancy by allowing multiple routers to share a virtual IP addres...
A router is a networking device that forwards data packets between computer networks, while a firewall is a security system that monitors and controls incoming and outgoing network traffic.
Router directs traffic between different networks based on IP addresses.
Firewall filters network traffic based on predetermined security rules.
Routers operate at layer 3 (network layer) of the OSI model, while firewalls operate at la...
DWDM stands for Dense Wavelength Division Multiplexing, a technology used in fiber optic communications.
DWDM is a technology that allows multiple data signals to be transmitted simultaneously over a single fiber optic cable.
Components of DWDM include lasers, multiplexers, demultiplexers, optical amplifiers, and dispersion compensators.
DWDM systems use different wavelengths of light to carry multiple data streams, incre...
The OSI reference model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven distinct layers.
The OSI model stands for Open Systems Interconnection model.
It helps in understanding how different networking protocols work together.
Each layer has specific functions and communicates with adjacent layers.
Examples of layers include physical layer, data link layer, net
