The test you will take will be related to the profile for which you are interviewing, such as sales or aptitude, meaning that it will assess your abilities and knowledge. It will evaluate your verbal language skills, reasoning capabilities, and overall eligibility. This test is designed to analyze your thought process, including how quickly you can solve the questions, as well as to measure your intelligence.
This test includes questions related to sales, such as how to create a pipeline, how to follow up with cold and warm leads, and how to shortlist leads. It also addresses customer handling, product pitching, and conditions for selling a product according to the customer’s needs, as well as how to highlight key points and features. Additionally, it discusses negotiation strategies, mathematical problems, questions related to English language passages, and techniques for solving math problems. Finally, it mentions that you will be given a paragraph or a task on which you are required to write about 400 to 600 words according to your understanding.

API Gateway implementation is a centralized service that routes, manages, and secures API calls.
API Gateway acts as a single entry point for all API calls
It can handle authentication, rate limiting, caching, and request/response transformations
Examples include AWS API Gateway, Apigee, Kong
Circuit breaker is a design pattern used to prevent system overload by temporarily stopping requests to a failing service.
Circuit breaker monitors requests to a service and opens when the service fails repeatedly.
It helps prevent cascading failures and allows the system to gracefully degrade.
Once the circuit breaker is open, it can periodically check if the service has recovered before allowing requests again.
Deadlock is a situation in which two or more processes are unable to proceed because each is waiting for the other to release a resource.
Avoid circular wait by ensuring processes request resources in the same order.
Prevent hold and wait by requiring processes to request all needed resources at once.
Implement a timeout mechanism to break potential deadlocks.
Use resource allocation graphs to detect and prevent deadlocks.

The equals() method is used to compare the contents of two objects for equality.
The equals() method is a method of the Object class in Java.
It is used to compare the contents of two objects for equality.
The default implementation of equals() in the Object class compares memory addresses, so it is often overridden in custom classes to compare content.
Example: String class overrides equals() method to compare the content

Hibernate handles the mapping of Java classes to database tables and vice versa, as well as the generation ...
Runnable is a functional interface with a single run() method, while Callable is a functional interface with a single call() method.
Runnable is used for tasks that do not return a result, while Callable is used for tasks that return a result.
Callable can throw checked exceptions, while Runnable cannot.
Callable returns a Future object, which can be used to retrieve the result of the computation.
Example: Runnable - execu...
The Callable interface in Java returns a Future object.
Callable interface returns a Future object which represents the result of a computation that may not be available yet.
The Future object can be used to retrieve the result of the computation, check if it is done, or cancel the computation.
Example: Callable<Integer> task = () -> { return 42; }
Monitor application health using metrics, logs, alerts, and performance monitoring tools.
Use monitoring tools like Prometheus, Grafana, or New Relic to track key metrics such as CPU usage, memory usage, response times, and error rates.
Implement logging to record important events and errors in your application. Use tools like ELK stack (Elasticsearch, Logstash, Kibana) for log analysis.
Set up alerts to notify you of any...
To call an API in a Microservice architecture, use HTTP requests or messaging protocols like gRPC.
Use HTTP requests to communicate between microservices
Implement RESTful APIs for easy integration
Leverage messaging protocols like gRPC for efficient communication
Consider using service discovery mechanisms for dynamic API calls
Profiles in Java are configurations that define the capabilities of a Java platform.
Profiles allow developers to target specific types of devices or applications.
They help in reducing the size of the Java runtime environment by including only the necessary APIs.
Examples include Java SE Embedded Profile for embedded devices and Java SE Compact Profile for resource-constrained environments.
OpenFeign is a declarative web service client used to simplify the process of making HTTP requests in microservices architecture.
OpenFeign allows developers to define RESTful web services as interfaces and automatically generate the necessary implementation code.
It integrates seamlessly with Spring Cloud and other microservices frameworks to facilitate communication between services.
OpenFeign supports features like loa...
Service registry and discovery involves registering services and allowing clients to discover and connect to them.
Implement a service registry where services can register themselves with metadata
Use a service discovery mechanism for clients to find and connect to services
Implement health checks to ensure services are available and healthy
Use a load balancer to distribute traffic among multiple instances of a service
Spring Boot Actuators are built-in tools that provide insight into the running application.
Actuators expose various endpoints to monitor and manage the application.
They can be used to check health, metrics, environment details, and more.
Examples include /actuator/health, /actuator/metrics, and /actuator/env.
Synchronous communication is blocking, while asynchronous communication is non-blocking.
Synchronous communication waits for a response before continuing, while asynchronous communication does not wait.
Examples of synchronous communication include traditional function calls, while examples of asynchronous communication include callbacks and promises.
Synchronous communication can lead to performance issues if there are d...
Synchronized keyword is used in Java to control access to shared resources by multiple threads.
Synchronized keyword can be applied to methods or code blocks to ensure only one thread can access the synchronized code at a time.
It prevents race conditions and ensures thread safety by creating a lock on the object or class.
Example: synchronized void myMethod() { // synchronized code block }
Excessive use of synchronized blocks and methods in Java can lead to performance issues and potential deadlocks.
Decreased performance due to increased contention for locks
Potential deadlocks if multiple threads are waiting for each other to release locks
Increased complexity and difficulty in debugging and maintaining code
Use synchronized sparingly and consider alternatives like ConcurrentHashMap or Lock interface
The number of threads needed for an application can be determined based on factors like the type of tasks, hardware resources, and performance requirements.
Consider the type of tasks your application needs to perform - CPU-bound tasks may benefit from more threads, while I/O-bound tasks may not.
Take into account the hardware resources available - more threads may be beneficial on a multi-core processor compared to a si...
Executor framework is a framework in Java that provides a way to manage and execute tasks asynchronously.
Allows for managing thread execution in a more efficient way
Provides a way to decouple task submission from task execution
Supports various types of executors like ThreadPoolExecutor and ScheduledExecutorService
Helps in handling tasks concurrently and asynchronously
BlockingQueue is an interface in Java that represents a queue which supports operations that wait for the queue to become non-empty when retrieving an element and wait for space to become available in the queue when adding an element.
BlockingQueue is part of the java.util.concurrent package.
It is used for implementing producer-consumer scenarios where multiple threads are involved.
Methods like put() and take() are used...
