Microservice is a software architecture pattern where an application is built as a collection of small, independent services.
Microservices are independently deployable and scalable.
Each microservice performs a specific business function.
Communication between microservices is usually done through APIs.
Microservices can be written in different programming languages and use different data storage technologies.

A Consumer Group is a group of consumers that collectively consume messages from one or more topics.
Consumer Groups allow for parallel processing of messages from a topic
Each consumer group maintains its own offset for each partition of a topic
Multiple consumer groups can consume messages from the same topic
Consumer Groups are commonly used in Apache Kafka
No, Kafka relies on ZooKeeper for cluster coordination and management.
ZooKeeper is used for leader election, configuration management, and synchronization in Kafka clusters.
Kafka brokers register themselves in ZooKeeper and use it to discover other brokers and partitions.
Without ZooKeeper, Kafka cannot function as a distributed system.
However, Kafka can be run in standalone mode without ZooKeeper for development and te
ZooKeeper is a distributed coordination service for managing configuration, synchronization, and naming.
ZooKeeper provides a hierarchical namespace for distributed systems.
It is used for maintaining configuration information, naming, providing distributed synchronization, and group services.
ZooKeeper is used in Apache Hadoop, Apache Kafka, and Apache Storm.
It uses a consensus protocol called ZAB (ZooKeeper Atomic Broad...
Replications ensure fault tolerance and high availability of data in Kafka.
Replications provide redundancy and ensure that data is not lost in case of node failures.
They also improve read performance by allowing consumers to read from multiple replicas.
Replications can be configured to have different levels of consistency guarantees.
For example, a replication factor of 3 ensures that data is stored on 3 different nodes...
Web services are software systems designed to support interoperable machine-to-machine interaction over a network.
Web services allow different applications to communicate with each other over the internet.
They use standardized protocols like HTTP, XML, SOAP, and REST.
Web services can be used for a variety of purposes, such as sharing data between different systems or integrating different applications.
Examples of web s...
Switch case is used for multiple conditions while if else is for binary conditions. Sorting can be done using various algorithms.
Switch case is faster than if else for multiple conditions
If else is more readable for binary conditions
Sorting can be done using bubble sort, insertion sort, quick sort, etc.
Example code for bubble sort: for(i=0;i
Difference between compiler and interpreter with a coding challenge
Compiler translates the entire code into machine language before execution while interpreter translates line by line during execution
Compiler generates an executable file while interpreter does not
Compiler is faster but debugging is harder while interpreter is slower but debugging is easier
Coding challenge: Write a program to find the sum of two numbers

You are provided with a singly linked list and an integer K
. The objective is to make the Kth
node from the end of the linked list the starting node of the linked list.
Given a singly linked list and an integer K, rearrange the list such that the Kth node from the end becomes the starting node.
Traverse the linked list to find the length and the Kth node from the end.
Update the pointers to rearrange the list accordingly.
Handle edge cases like K being equal to 1 or the length of the list.

The first line contains an...
Check if given strings containing parentheses are balanced or not.
Use a stack to keep track of opening parentheses
Iterate through the string and push opening parentheses onto the stack
When a closing parentheses is encountered, pop from the stack and check if it matches the corresponding opening parentheses
If stack is empty at the end and all parentheses are matched, the string is balanced

Given a sorted alien dictionary in an array of strings, determine the character order of the alien language.
Iterate through the dictionary to build a graph of character dependencies based on adjacent words.
Perform a topological sort on the graph to determine the character order.
Return the character array representing the order of characters in the alien language.
You are given an array/list CHOCOLATES
of size 'N', where each element represents the number of chocolates in a packet. Your task is to distribute these chocolates among 'M'...
Distribute chocolates among students to minimize the difference between the largest and smallest number of chocolates.
Sort the array of chocolates in ascending order.
Iterate through the array and find the minimum difference between the elements by considering 'M' elements at a time.
Return the minimum difference found as the result.

You are provided with a square matrix of non-negative integers of size 'N x N'
. The task is to rotate this matrix by 90 degrees in an anti-clockwise directi...
Rotate a square matrix by 90 degrees anti-clockwise without using extra space.
Iterate through each layer of the matrix from outer to inner layers
Swap elements in groups of 4 to rotate them in place
Handle odd-sized matrices separately by adjusting the loop boundaries
Given a binary string S
of length N
where initially all characters are '1', perform exactly M
operations, choosing from four specific operations, and determine how many dis...
Count the number of distinct final strings possible after performing a given number of operations on a binary string.
Iterate through all possible combinations of operations to determine the final string after each operation.
Use bitwise operations to efficiently flip the bits based on the chosen operation.
Keep track of distinct final strings using a set data structure.
Return the size of the set as the number of distinct

is the firs...
Find the Next Greater Element for each element in a list of integers.
Iterate through the list of integers from right to left.
Use a stack to keep track of elements for which the Next Greater Element is not yet found.
Pop elements from the stack until a greater element is found or the stack is empty.
Assign the Next Greater Element as the top element of the stack or -1 if the stack is empty.
Tip 1 : Practice Medium level question.
Tip 2 : Do atleast 2 projects

Tip 1 : First go through your own resume very well as most of the company first ask questions from one's resume. Prepare what to say if they ask you about the projects you mentioned in your resume that's why never fake your resume. Be confident with what you have
Tip 2 : Obviously if you are applying for software developer role you should have basic concepts of the programming languages you learned in your college days like C, C++, Java etc if you don't know a little too then I suggest you to learn some basics first in any particular language and then practice them in IDE. As now most of the interviews are virtual so it's good to practice writing code in IDE as they often can ask you to solve some basci questions like string reversal, check palindrome or not like that.
Tip 3 : You should have good communication skill. Good communication doesn't mean fluent english communication means interact with the receuiter in such a manner that he can understand the point you are trying to mark. Be confident, don't lie in any ways if you don't have correct answe for a question and you know that directly say NO you don't know this answer rather than replying with stupid answers and other side recruiter gets a little bit disappointed as you wasted some times of him for this kind of answer. If you know the answer instead of saying fluently try to speak the sentences with a little pause that makes recruiter understand that you really understand the topic you are talking about and that will be impressive.
Tip 1 : Don't fake your resume
Tip 2 : Try to do good projects and mention them in resume
Tip 3 : As a fresher I suggest to prepare a resume of maximum
2 pages.
The duration of LTIMindtree Software Developer interview process can vary, but typically it takes about less than 2 weeks to complete.
