Software engineering is a lucrative job, and it requires hard work and dedication to become one. Becoming aware of QUESTIONS ASKED in interviews can really help a lot. We covered software engineering questions that can help you crack that interview. The above LIST of relevant questions can only be a guideline. We cannot predict the exact problem that may pop up during the interview, but we hope that the general architecture and design knowledge gained from them would be helpful for you.

When a piece of software is created, there is always room for improvement. To modify or improve an existing SOLUTION or to ESTABLISH a new solution for a problem, changes may be required. Changes to the existing system should be examined before being IMPLEMENTED, recorded before being implemented, documented with details of before and after, and controlled in a way that improves quality and reduces error. This is where System Configuration MANAGEMENT is required.

During the Software Development Life Cycle, Software Configuration Management (SCM) is a TECHNIQUE for systematically managing, organizing, and controlling changes in documents, codes, and other entities. The main goal is to enhance production while making as few mistakes as possible.

Modularization is ‌breaking down a program's functionality into SEPARATE, independent modules, each of which includes just the information needed to carry out one part of the intended capability. In simple terms, it is the practice of dividing the program into smaller modules so that we can deal with them separately. We can simply add independent and smaller modules to a program USING modularization without being hampered by the complexity of the program's other functionalities. Modularization is BASED on the notion of designing applications that are easier to develop and maintain, self-contained components. In monolithic design, on the other hand, there's always the risk of a simple change knocking the entire application down. The final STEP would be to COMBINE these independent modules.

In the above diagram, both the applications have been divided into smaller modules. These modules can then be dealt with separately.

A SOFTWARE metric is a quantitative measure of program properties. Software metrics can be used for a RANGE of THINGS, such as analyzing software performance, planning, estimating productivity, and so on. Load testing, stress testing, AVERAGE failure RATE, code complexities, lines of code, etc. are some software metrics. The benefits of software metrics are many, some of them being:

• It reduces cost.
• It increases ROI (return on investment).
• Reduces workload.
• Highlights areas for improvement.

In software engineering, concurrency REFERS to a SET of techniques and mechanisms that allow the software to do many tasks at the same time. Concurrency can be achieved by using languages like C++ or Java because these languages support the concept of THREAD. New HARDWARE and software features are required to achieve concurrency. 

• Black box testing is a type of high-level testing in which the primary goal is to evaluate functionalities from a behavioural standpoint. In black-box testing, the tester does not test the code; instead, they utilize the program to see if it works as expected.
• When you have insight into the code or broad information about the ARCHITECTURE of the software in QUESTION, you can perform white box testing, also known as clear box testing. It falls under the category of low-level testing and is mostly concerned with integration and unit testing.  White box testing requires programming EXPERTISE or at the very LEAST a THOROUGH grasp of the code that implements a particular functionality.

As the name implies, a FEASIBILITY study is a measurement of a software product in terms of how useful product development will be for the business from a practical STANDPOINT. Feasibility studies are conducted for a variety of REASONS, including determining whether a software product is appropriate in terms of development, IMPLEMENTATION, and PROJECT value to the business. The feasibility study concentrates on the following areas:

• Economic feasibility
• Technical feasibility
• Operational feasibility
• Legal feasibility
• Schedule feasibility
