Answer: A feasibility study is conducted on a software product to assess how practical and beneficial is the development of the software product to the organization. Requirement Gathering, System Analysis, Design, Coding, Testing, Maintenance, and Documentation. Midway through the problem, he makes a little error -- getting the order of operations wrong on the first try, or having an off-by-1 error, or forgetting to declare a variable. Defects raised at this phase need to be fixed before providing sign off on the product. Answer: The answer to this question depends on the experience of an interview candidate. It is a document to capture all the functional and non-functional requirements of a product. Enlisted below are the most frequently asked Software Engineer Interview Questions with answers. Answer: There are no rules as such stating which specific SDLC model has to be used for a software product. It depends on the type of software project being built and the organization’s policies & procedures. Answer: V-Model stands for the verification and validation model. Q #21) What do you mean by Software Scope? Baselines are used to track the progress of the project from time to time to assess the overall health of the project. Q #15) How can you measure Project execution? Any change made during software development has to be tracked through a well-defined and controlled process. An architecture expresses a fundamental structural organization schema for software systems. The final result would be to combine multiple modules into a single working component. Answer: The following are the most common phases of SDLC. If the candidate answers the SDLC model to be the Waterfall model, then the interviewer will start asking questions about the Waterfall model and if he answers it to be Agile, then the interviewer will start asking terms related to Agile methodology such as Scrum, Sprint, etc. Also, Read => Quality Assurance Vs Quality Control. This is the most important phase of SDLC as a clear understanding of requirements from the client will reduce the rework in the following phases. Software engineering programs do not stress computer hardware and electronics as much as computer engineering programs do. Q #24) Explain the Waterfall model in detail. Unit Testing and Integration Testing must be performed by the developers at this stage before deploying the code for testing. Answer: A Software Project Manager is responsible for driving the project towards successful completion. It is a very common myth that SE is mainly programming. Q#7) Explain the concept of Modularization. Answer: Software configuration management is the process of tracking and controlling the changes that occur during the software development lifecycle. It is the responsibility of the Software Project Manager to make sure the entire team follows a systematic and well-defined approach towards the development of software. In sequence Diagrams, we show respective class names by a small box and the event as a arrow. Good software has high levels of cohesion. This testing is generally performed by the developer who has written the code in the form of unit tests. Q #16) What are the Functional Requirements? There are no hard and fast rules as such on the type of Software Engineering interview questions asked by interviewers. The duration of the maintenance phase differs from project to project and one organization to another. Then comes the high-level design and the detailed level design phases where the architecture of the system is prepared. Initially, requirements are gathered to document the system to be developed as per the client requirements. All the best for your software engineer interview!! A software project manager is also responsible for the following tasks: Answer: Cohesion is the degree to which the elements of a module are inter-related to one another. Software Engineering is all about using engineering principles for the production of software. Answer: A baseline is a milestone on the project which is usually defined by the project manager. Good software has low levels of coupling. Answer: Project execution status can be monitored using the following techniques. Answer: Modularization is used to divide software into multiple components or modules. Once the coding is complete on SDLC, STLC will start from unit testing, followed by integration testing and System testing. The software scope defines all functionalities and artifacts to be delivered as a part of the software. Recommended Read => Top Project Management Tools That You Should Know. Use cases are graphical represenation of system parts and there interaction that is taking place. Answer: Functional requirements are the features that a developed software product is expected to perform. Answer: The waterfall model is a sequential model in which the next phase starts only after the first phase is completed. Any previous programming experience that you may have is certainly an asset, but it is not a requirement. a) Requirements: This is the phase where the system to be developed is documented in the form of Software Requirement Specification (SRS) document. V-model is an addition to the waterfall model, in the sense that V-model is also a sequential model. Quality Assurance is done by the testing team of the project while Quality Control is usually done by a dedicated support team, who is responsible for the quality of the product even if the product is under the maintenance phase of software engineering. Quality Control is the process of ensuring that the quality of the product is maintained in the long run. Software Engineering is the application of a systematic, disciplined and quantifiable approach to the development, operation, and maintenance of software. Answer: Black box testing involves testing the application without the knowledge of the internal structure or code implementation. Answer: Coupling is the degree of interdependence between the modules. Given below is the high-level representation of the various phases involved in SDLC. The testing team prepares the Integration Test plan in these phases. Normally we depict. A software engineering interview covers a range of topics, from technical to problem-solving and behavioral. As the phases form the shape of the letter ‘V’, this model is called V-Model. These questions and answers will help you strengthen your technical skills, prepare for the new job test and quickly revise the concepts. Q #10) Provide examples of Project Management tools.
