I am currently working with Java and Selenium for test automation.
Using Java programming language for writing test scripts
Using Selenium WebDriver for automating web applications
Integrating with CI/CD tools like Jenkins for continuous testing
Working with frameworks like TestNG for test management
Using tools like Maven for project management
Find the maximum subsequent distinct and contiguous subarray in a character array.
Use a sliding window approach to iterate through the array.
Keep track of the distinct characters in the current subarray.
Update the maximum length and subarray as necessary.
Create a stack using 2 given queues.
Push elements into one queue until it is full.
When the first queue is full, push new elements into the second queue.
To pop an element, remove all elements from the non-empty queue except the last one.
Switch the non-empty queue to the other one when it becomes empty.
A test framework should have features like test case management, test data management, reporting, and integration with CI/CD tools.
Test case management: Ability to create, organize, and execute test cases.
Test data management: Ability to manage test data and generate test data sets.
Reporting: Ability to generate detailed test reports with metrics and logs.
Integration with CI/CD tools: Ability to integrate with tools li...
To check if each page of Amazon.com has its logo, we can use automated testing with Selenium WebDriver.
Use Selenium WebDriver to navigate to each page of Amazon.com
Locate the logo element on each page using its XPath or CSS selector
Verify that the logo element is displayed on each page
Yes, I have worked on automation frameworks.
I have experience in developing and maintaining automation frameworks using tools like Selenium, TestNG, and Cucumber.
I have also worked on customizing existing frameworks to meet specific project requirements.
I am familiar with both data-driven and keyword-driven frameworks.
I have integrated automation frameworks with CI/CD pipelines for continuous testing.
One example of a p...
When entering a URL and hitting enter, the browser performs DNS lookup, establishes a TCP connection, sends an HTTP request, receives the response, and renders the page.
Browser performs DNS lookup to resolve the domain name to an IP address
Browser establishes a TCP connection with the server
Browser sends an HTTP request to the server
Server processes the request and sends back an HTTP response
Browser receives the respon
Reverse every 3 nodes in a singly linked list using recursion.
Create a recursive method that takes the head of the linked list as input.
If the head is null or there are less than 3 nodes remaining, return the head.
Reverse the first 3 nodes by swapping their pointers.
Recursively call the method on the next 3 nodes and update the pointers accordingly.
Return the new head of the reversed linked list.
1. Time management 2. Public speaking 3. Learning new technologies
Struggling with time management, often missing deadlines
Nervous when speaking in front of large groups
Finding it challenging to keep up with the latest technologies in the field
Program to find the angle between the hands of a clock given the time.
Calculate the angle of the hour hand from 12 o'clock position
Calculate the angle of the minute hand from 12 o'clock position
Calculate the absolute difference between the two angles
If the difference is greater than 180 degrees, subtract it from 360 degrees
Return the absolute value of the difference as the angle between the hands
To find if two linked lists intersect, traverse both lists and compare their tail nodes.
Traverse both linked lists and find their lengths
If the lengths are different, move the longer list's head pointer to the difference in length
Now traverse both lists and compare their nodes until a common node is found
If no common node is found, the lists do not intersect
JOINS are used to combine rows from two or more tables based on a related column between them.
JOINS are used to retrieve data from multiple tables in a single query
There are different types of JOINS - INNER, LEFT, RIGHT, FULL OUTER
JOINS are based on a related column between the tables
Syntax: SELECT * FROM table1 JOIN table2 ON table1.column = table2.column
Combine 4 elements of a sorted array of size 7 and a sorted array of 3 elements to make a sorted array.
Insert the 3 elements of the smaller array into the larger array
Sort the larger array using any sorting algorithm
To check if a string is a palindrome, compare the first and last characters, then move towards the center.
Remove all non-alphanumeric characters and convert to lowercase
Use two pointers, one starting from the beginning and the other from the end
Compare the characters at both pointers, move towards the center until they meet
If all characters match, the string is a palindrome
I applied via Company Website and was interviewed in Oct 2021. There were 3 interview rounds.
Find the first and last occurrence of a specific element in an array of strings.
Iterate through the array and keep track of the index of the first and last occurrence of the element.
Return the index of the first and last occurrence of the element.
Find pair of elements in an array whose sum is equal to a given number K.
Iterate through the array and for each element, check if K minus the element exists in the array.
Use a hash table to store the elements and their indices for faster lookup.
If multiple pairs exist, return any one of them.
If no pair exists, return null or an appropriate message.
Session is maintained using session affinity or sticky sessions.
Session affinity ensures that a user's session is always directed to the same server.
Load balancer uses a unique identifier to route requests to the same server.
Sticky sessions can be implemented using cookies or URL rewriting.
Session replication can also be used to maintain session data across multiple servers.
Singleton pattern ensures only one instance of a class is created and provides a global point of access to it.
Create a private constructor to prevent direct instantiation of the class
Create a private static instance of the class
Create a public static method to access the instance
Ensure thread safety by using synchronized keyword or static initialization block
Examples: Logger, Configuration Manager, Database Connection
Explaining abstract class, interface and multiple inheritance in PHP.
Abstract class is a class that cannot be instantiated and can have abstract methods.
Interface is a collection of abstract methods and constants that can be implemented by a class.
Multiple inheritance is not possible in PHP, but can be achieved using interfaces.
Interfaces can be implemented by multiple classes, allowing for multiple inheritance-like be

Identify the tables and their relationships
Determine the conditions to be used in the stored procedure
Write the SQL code for the stored procedure
Test the stored procedure to ensure it returns the desired results
To increase PHP memory at run time, modify the php.ini file or use ini_set() function.
Edit the memory_limit value in php.ini file
Use ini_set('memory_limit', '256M') function to increase memory limit at run time
Check for memory leaks in the code
Use unset() function to free up memory after use
php.ini is a configuration file for PHP that allows users to customize various settings.
Change PHP settings such as memory limit, file upload size, and error reporting
Enable or disable extensions and modules
Set timezone and language settings
Configure email settings
Control caching and session settings
Use window.location to get domain from a url in jQuery.
Use window.location to get the full url
Use .hostname to get the domain name
Use .replace() to remove 'www.' if present
WAP to find smallest palindrome number larger than given number.
Convert the given number to string and check if it is already a palindrome.
If not, increment the number and check if it is a palindrome.
Repeat until a palindrome number larger than the given number is found.
Use a while loop to implement the above steps.
WAP to check if linked list elements is a palindrome without using any extra space.
Traverse the linked list and reverse the second half of the list
Compare the first half with the reversed second half
Use two pointers to traverse the list, one at normal speed and other at double speed
