10+ TCS Interview Questions and Answers

Communication between multiple micro services can be achieved through various methods such as REST APIs, message queues, gRPC, and event-driven architecture.

• Use REST APIs for synchronous communication between micro services.

• Implement message queues like RabbitMQ or Kafka for asynchronous communication.

• Utilize gRPC for efficient communication between services.

• Adopt event-driven architecture using tools like Apache Kafka or Amazon Kinesis.

Securing APIs involves using authentication, authorization, encryption, and monitoring.

• Implement authentication mechanisms such as OAuth or API keys

• Use authorization to control access to different parts of the API

• Encrypt data transmission using HTTPS

• Regularly monitor API traffic for suspicious activity

• Keep API documentation updated to reflect security measures

Comparing objects involves identifying similarities and differences between them.

• Both objects have attributes and behaviors

• Objects can be classified into categories based on their similarities

• Objects can be compared based on their properties and methods

AML monitoring focuses on identifying and preventing money laundering activities, while transaction monitoring involves monitoring individual transactions for suspicious or fraudulent activities.

• AML monitoring is a broader process that involves monitoring customer behavior and transactions to detect and prevent money laundering.

• Transaction monitoring is a subset of AML monitoring and focuses on monitoring individual transactions for suspicious or fraudulent activities.

• AML mon...read more

Depreciation is the decrease in value of an asset over time. Various methods include straight-line, declining balance, and sum-of-the-years' digits.

• Depreciation is a way to allocate the cost of an asset over its useful life.

• Straight-line depreciation is the simplest method, where the same amount is depreciated each year.

• Declining balance depreciation is an accelerated method, where a higher percentage of the asset's value is depreciated in the early years.

• Sum-of-the-years' di...read more

Amazon Web Services (AWS) services commonly suggested for migration include EC2, S3, RDS, and Lambda.

• EC2 (Elastic Compute Cloud) for scalable virtual servers

• S3 (Simple Storage Service) for scalable object storage

• RDS (Relational Database Service) for managed databases

• Lambda for serverless computing

My expected CTC is negotiable based on the responsibilities and opportunities offered in the role.

• My expected CTC is based on my experience, skills, and the market rate for the position.

• I am open to discussing the compensation package and benefits provided by the company.

• I am looking for a competitive salary that reflects my qualifications and contributions to the team.

OOPs is a programming paradigm based on the concept of objects, which can contain data and code.

• OOPs stands for Object-Oriented Programming.

• It focuses on creating objects that interact with each other to solve a problem.

• The four main concepts of OOPs are encapsulation, inheritance, polymorphism, and abstraction.

• Encapsulation is the process of hiding the implementation details of an object from the outside world.

• Inheritance allows a class to inherit properties and methods from...read more

Shrinkage can be controlled through effective inventory management, employee training, security measures, and regular audits.

• Implementing strict inventory management processes to track all products entering and leaving the store

• Providing thorough training to employees on how to identify and prevent theft

• Installing security measures such as surveillance cameras, security tags, and alarm systems

• Conducting regular audits to identify any discrepancies in inventory levels

Bending and torsional stiffness are mechanical properties that describe a material's resistance to deformation under bending and twisting forces.

• Bending stiffness refers to a material's ability to resist deformation when subjected to bending forces.

• Torsional stiffness refers to a material's ability to resist deformation when subjected to twisting forces.

• These properties are important in engineering design to ensure structural integrity and stability.

• Examples include beams in ...read more

Generic patterns refer to common design structures or solutions that can be applied across different contexts or scenarios.

• Generic patterns help in creating reusable and scalable solutions.

• They provide a framework for solving similar problems in various situations.

• Examples include design patterns like Singleton, Factory, and Observer.

• Generic patterns can be applied in software development, architecture, and even project management.

Java 8 introduced several new features including lambda expressions, streams, functional interfaces, and default methods.

• Lambda expressions allow for more concise code and easier parallel programming.

• Streams provide a way to work with sequences of elements and support functional-style operations.

• Functional interfaces enable the use of lambda expressions to represent single-method interfaces.

• Default methods allow interfaces to have method implementations.

• Other features include...read more
