As with any subjective question, there can be strong opinions on the topic. While answers should be stated confidently and with supporting experiences, it is very easy to slip into speaking negatively about your less-favored approach. The interviewer could have the opposite opinion, creating avoidable tension. Focusing on objective obstacles you face with the approach will avoid the situation and potentially open a friendly dialogue on the pros and cons of each.
It used an imperative, object-oriented approach with many of the custom controls getting much of their functionality from a growing inheritance hierarchy. We took this as an opportunity to shift to a more declarative approach.
After the conversion, we saw a dramatic decline in state-related bugs as we were no longer manually updating the interface in response to events. This had previously been the most common type of user-reported bug.
We did, however, have to make adjustments in a few key places. In more dynamic, performance-sensitive portions of the application, the caching mechanisms we implemented to prevent excessive recalculation were becoming overly complex.
We simplified this by switching back to an imperative approach to updating the component. Similar to the previous question, this probes your knowledge of more abstract, theoretical concepts. Very few people are familiar with all of the formalized software design patterns. In fact, many well-established engineers have a hard time even naming more than a few. After reviewing the topic, you may realize that you leverage many of these patterns daily, even if you aren't aware of the formal name.
Reviewing these concepts helps provide a common shorthand, streamlining complex discussions. Example: "For gaming projects, my level state and player character are generally implemented as singletons. Additionally, the bullets being fired by the character will be implemented in an object pool to avoid performance hits from excessive instantiation and garbage collection.
If the game is more complex, I may switch to a compositional model such as Entity-Component-System. The system functions would then leverage dependency injection to better separate concerns and increase testability of the game logic. Process is an extremely important component of software development. Since its inception, growing numbers of companies have adopted the methodologies in some form. However, there are a wide range of opinions and interpretations on the subject.
And there are yet others who wholly disagree with the philosophy. No matter your opinion, wide industry adoption means you will likely work within the framework at some point in your career. You should be capable of articulating the details of the process. Try using concrete examples from your experience. In your answer, address areas of the process such as:.
Example: "Agile software development is a process that focuses on incremental delivery by the team as a whole. We used two-week sprints and kept high contact with many face-to-face discussions to review questions and concerns as they arose. In addition, we had daily standup meetings to keep everyone synced on team progress. The only adjustment to the process I would have made was in regard to our standup meetings.
However, our meetings tended to transition over into standard status meetings for our team lead rather than remaining a time for our team to sync. Other than this, the process really did facilitate delivering higher quality software on a more predictable timetable. Testing is an extremely important component of the software development life cycle because it ensures the quality of the software before it is deployed to users. There are other approaches that enumerate particularly complex or sensitive code and write a test for those as opposed to every line.
You should have informed opinions on why you favor one approach over another. It will demonstrate that you are aware of the range of methodologies and have made a choice based on sound reasoning.

Frame your answer in a way that demonstrates yourself a suitable candidate for the job.
You may want touch on your career experiences, your software engineering skills, your achievements or your passion for software engineering. During this time, I have managed numerous complex software engineering projects. Most recently, I developed a software solution for a major holiday company. When I was at high school, I used to develop my own video games and share them with my friends. Many people find this a daunting question.
To give yourself the best chance of making a positive impression on interviewers when answering this question, conduct research into the company.
This will enable you to tailor your answer. As someone who is passionate about professional development and improving my capabilities, I would love to work for a company that rewards this. Also, I recently learned that this company takes steps to involve itself in the local community. I am also passionate about volunteering, and I regularly volunteer at a local soup kitchen in my area.
I feel that our values are aligned on this issue. Interviewers want to know about your your level of proficiency with these programming languages. Examine the job description to find out which programming languages the company is looking for. Stated simply, the hardware begins to wear out.
Software is not susceptible to the environmental maladies that cause hardware to wear out. When a hardware component wears out, it is replaced by a spare part. There are no software spare parts.
Every software failure indicates an error in design or in the process through which design was translated into machine-executable code. Therefore, the software maintenance tasks that accommodate requests for change involve considerably more complexity than hardware maintenance. But it does deteriorate. The software continues to be custom-built: A software part should be planned and carried out with the goal that it tends to be reused in various projects.
Current reusable segments encapsulate the two information and the preparation that is applied to the information, empowering the programmer to make new applications from reusable parts.
In the hardware world, component reuse is a natural part of the engineering process For more details please refer to the following article Software Engineering Characteristics. What activities come under the umbrella activities? The activities of the software engineering process framework are complemented by a variety of higher-level activities. Umbrella activities typically apply to the entire software project and help the software team manage and control progress, quality, changes, and risks.
What is Cohesion and Coupling? Cohesion indicates the relative functional capacity of the module. Aggregation modules need to interact less with other sections of other parts of the program to perform a single task.
It can be said that only one coagulation module ideally needs to be run. Cohesion is a measurement of the functional strength of a module. A module with high cohesion and low coupling is functionally independent of other modules. Here, functional independence means that a cohesive module performs a single operation or function.
The coupling means the overall association between the modules. Coupling relies on the information delivered through the interface with the complexity of the interface between the modules in which the reference to the section or module was created. High coupling support Low coupling modules assume that there are virtually no other modules. It is exceptionally relevant when both modules exchange a lot of information.
The level of coupling between two modules depends on the complexity of the interface. For more details, please refer to the following article Coupling and cohesion. What are the various phases of SDLC? What is the name of various CASE tools? What is Black box testing? The black box test also known as the conducted test closed box test opaque box test is centered around software useful prerequisites.
In other words, it is possible to guess a set of information conditions that help the program through an attempt to discover and fulfill all the necessities perfectly. There is no choice of black-box testing white box procedures. What is White box testing? White Box Testing is a method of analyzing the internal structure, data structures used, internal design, code structure, and behavior of software, as well as functions such as black-box testing.
Also called glass-box test or clear box test or structural test. What is a Feasibility Study? The Feasibility Study in Software Engineering is a study to assess the adequacy of proposed projects and systems. A feasibility study is a measure of a software product on how product development can benefit an organization from a validity analysis or practical point of view. For more details, please refer to the following article Types of Feasibility Study in Software Project Development article.
It focuses on fulfilling the quality requested. It is the technique of managing quality. It is the technique to verify quality. It does not include the execution of the program. It always includes the execution of the program. It is a managerial tool. It is a corrective tool. It is process-oriented. It is product-oriented. The aim of quality assurance is to prevent defects.
The aim of quality control is to identify and improve the defects. This testing is implement at the developer's site. Beta test: The beta testing is a testing in which the customer tests the version of the software without the developer being present. This testing is performed at the customer's site. There are the three types of static testing tools. Code-based testing tools: These tools take source code as input and generate test cases.
Specialized testing tools: Using this language, the detailed test specification can be written for each test case. Requirement-based testing tools: These tools help in designing as per user requirements.
