4) How do you choose a database to store information and how do you define it?

It's important to think about what kind of information the databases hold. It will help figure out how the database should be set up and what kinds of data need to be stored. It is important to think about the cost and resources needed to set up and run the database. It will help make sure that the database is both cheap and able to grow.

5) How do you track down task owners who modify software?

There are a few ways to identify task owners who make changes within a software program. One way is to look at the change logs for the program. It will show who made what changes and when they were made. Another way is to ask the people who work on the program directly.

6) Which software testing tools do you prefer?

There are a variety of tools available for testing software code. Junit or TestNG is powerful and easy to use for unit testing. For Functional Testing, Selenium allows us to automate the testing process and get complete results.

7) How do you use algorithms to find and recognize class-specific terms in linked lists?

A few algorithms can locate and identify class-specific terms in linked lists. One common approach is using a search algorithm, such as a breadth-first or a depth-first search, to traverse the list and locate the desired term. Another method is to use a sorting algorithm to sort the list in order of class specifically, then search through the sorted list for the selected term.

8) How would you use object-oriented design to improve the functionality and speed of an application?

Object-oriented design can improve the functionality and speed of an application in several ways. Breaking the application into smaller, more manageable objects can make the code more organized and easier to understand.

9) How would you approach organizing and delegating large objects?

The best way to Organize and Delegate large objects is to create a system where each object is assigned to a specific category. The category is used to track the object and its whereabouts.

10) How do you apply architectural principles to Software and framework design?

The best approach is to use well-known patterns and antipatterns to guide design decisions. Another approach is to use formal methods to verify that a design meets specific correctness criteria. Another possibility is to use domain-specific languages or notations to express architectural concepts more precisely and concisely.

11) Explain cloud components?

The term "component" can apply to many items in the cloud, including the storage, back end, front end, network, services, data centers, virtual machines, etc.

12) Define the CAP theorem?

The CAP theorem states that distributed computing systems can only provide two of the following guarantees.

  • Consistency: even with concurrent updates, all nodes still view the same data.
  • Availability: Every request is met with a successful or failed answer; therefore, it can be relied on to always be available.
  • Partition tolerance: If there is a break in communication between two nodes, the system will continue to function normally.

13) What do you mean by technical expertise?

Technical expertise refers to the knowledge and skills required to perform specific tasks and use specific tools and programs in real-world situations.

14) What is the BASE property of a system?

BASE properties are the common properties of recently evolved NoSQL databases. It is a contrived acronym mapped to the following property of a system in terms of the CAP theorem.

15) What are Heuristic Exceptions?

A Heuristic Exception is a decision made by a transaction participant to take action unilaterally without the agreement of the transaction manager, between the participant and the transaction manager, and there is a catastrophic failure.

16) What is Shared Nothing Architecture?

A distributed computing strategy known as a Shared Nothing Architecture is one in which every node in the system is autonomous and independent, and there is no requirement for a central point of contention anywhere within the network.

17) Why do you need clustering?

Clustering is required for the high availability of server software. Typical server software can run on a single computer and serve as long as there is no hardware failure or other failure. By forming a cluster of multiple machines, we can reduce the likelihood of our service becoming unavailable if one of the machines fails. The primary goal of clustering is to achieve 100% uptime or zero downtime in service.

Clustering only sometimes guarantees that a service will be 100% available because all of the machines in a cluster can fail at the same time. However, this is unlikely if you have many devices, each of which is located in a different location and is supported by its own resources.

18) What are the four types of System Tests?

There are four main stages of system tests. They are as follows-

  1. Unit testing
  2. Integration testing.
  3. System testing.
  4. Acceptance testing.

19) What is Load Balancing?

Load balancing is a simple way to spread work across multiple machines or groups of devices. In this type of load balancing, requests are split up and sent to different machines in a circle. This ensures that all machines get the same number of requests and that none are overloaded or underloaded. Round Robin is the most common and simple way to spread out the load.


What is Load Balancing?


20) Why is the CAP theorem helpful?

The CAP theorem is used for Consistency, Availability, and Partition Tolerance. Only two of these three requirements may be guaranteed to be satisfied by any given system. This theory laid the groundwork for contemporary distributed computing methods. Companies with the most daily visitors (like Amazon) use this to guide their decisions on the design of their applications.

22) What are the responsibilities of a Software Architect?

A software architect is responsible for designing, developing, and deploying software applications. They work with teams of developers to create software that meets the needs of their clients or employers. Software architects must have a strong understanding of computer systems and software development practices. They must also be able to communicate effectively with clients and other stakeholders.

23) What are the key skills required for a Software Architect?

The skills required for a software architect are communication, problem-solving, and leadership. Communication is essential because the architect needs to be able to articulate their ideas and explain them to others. Problem-solving is necessary because architects often need to find solutions to complex problems. Leadership is required because architects often need to guide and motivate their teams.

24) What education is required to become a Software Architect?

The educational requirements can vary depending on the specific industry and company you want to work for. Most software architects generally have a bachelor's degree in computer science or a related field. Additionally, many software architects have a Master's Degree or higher and have professional experience working in the software development field before becoming an architect.

25) Define Microservice Architecture?

An architectural style known as microservices, sometimes known as microservice architecture, is a design that organizes an application as a collection of tiny, independent services that are modeled after a business domain.

26) Why do we use WebSocket over HTTP?

A Web socket is an ongoing connection between the client and the server. It is called "Server Push" and is very valuable for applications.


Why do we use WebSocket over HTTP


27) What do you mean by interaction with a lower latency?

The term "low latency" refers to how quickly a request is fulfilled once it is made. Since the WebSocket connection is already established, no additional packet round trips are needed to create the TCP connection, allowing faster data transfer rates (especially over sluggish lines).


Network latency


28) Defining what "coupling" implies in Software Architecture.

The term "coupling" describes the interdependence of different modules or parts.

A high degree of interdependence between the two modules indicates that they are firmly coupled. They are less reliant on one another if they are only loosely attached. The degree of dependence between two modules is reduced if they may be disconnected from one another.

29) What is domain-driven design?

Domain Driven Design (DDD) is a technique and process prescription for designing complex systems that focuses on mapping actions, processes, events, and data from a problem domain into solution domain technological artifacts.

30) What is meant by the KISS principle?

In software architecture, "Keep It Simple, Stupid" (KISS) means that a system will work best when its developer or architect keeps things simple. KISS says that architects shouldn't make designs that are too complicated.

According to the KISS principle, complexity should be avoided in favor of simplicity in design. It is because, in most cases, a system will function better if it is maintained rather than made more sophisticated.

31) What is Elasticity?

Elasticity is the ability of a system to dynamically adjust its throughput up or down in response to changes in demand as resources are proportionally added or subtracted. The system must be scalable to profit from the dynamic addition or removal of resources at runtime. Therefore, elasticity extends scalability by introducing the idea of automatic resource management.

32) How do you handle giving tasks to other people?

Finding the right balance between giving away all tasks and doing everything on your own is important. Taking charge of your own life is essential, but so is relying on your team.

Watch out for candidates who make it clear that it's important to keep an eye on the team and the tasks that have been given to them.

33) What is orchestration in Software or the cloud?

Orchestration can be defined as the automatic configuration, coordination, and management of computer applications, systems, and services.

Software Architect Interview Preparation Tips

1. Prepare Thoroughly

Start by making a plan for how you will handle the interview. Don't just go with the flow! Even though you have to be ready to change on the spot, you'll be less nervous and do better if you have a plan before you start. At the very least, you should have a job description that you can use to figure out what technical skills to talk about. 

2. Make a Good First Impression

Smile! It's easy to connect with someone simply by flashing a kind smile; most people will reciprocate the gesture. Make sure your grin is genuine, though. A genuine smile will begin to fade gradually rather than abruptly.

3. Be polite to everyone

Yes, Absolutely! With every person! Always put on your best grind and be cordial to coworkers. After interviewing you, your prospective employer may inquire how you fared with current staff.

4. Be prepared for your interview.

Take your job search seriously by always being prepared with a resume, cover letter, and references. Your ability to stay on top of things will stand out to a prospective employer.

5. Ask for the Job!

Hiring managers often choose enthusiastic candidates. If you're still interested, say so after the interview. Say something like, "I really appreciate what I've heard today and would like to explore this opportunity further," or "I'm interested in joining a team like yours; what's the next step?"
