10 preguntas habituales en las entrevistas a ingenieros de software en 2023

1. What are the different categories of software?

There are several different categories of software, including:

1. System software: This type of software includes the operating system, device drivers, and other software that controls the underlying hardware of a computer or device.
2. Application software: This software is designed to perform specific user tasks, such as word processing, spreadsheets, and video editing.
3. Utility software: This type of software includes tools that help maintain and optimize the performance of a computer or device, such as antivirus programs, disk defragmenters, and backup software.
4. Embedded software: This software controls devices and systems that are not typically considered computers, such as smartphones, routers, and cars.
5. Firmware: Firmware is software embedded into a hardware device and provides low-level control of the device's functions.
6. Game software: This software is designed to entertain users, such as video games, mobile games, and online games.
7. Web-based software: This software is accessed through a web browser and runs on a web server, such as online word processors and project management tools.
8. Artificial Intelligence (AI) software uses machine learning, natural language processing, and other AI technologies to automate tasks, analyze data, and make decisions.

2. Briefly describe the software development process.

The software development process is a set of steps that software developers follow to create, design, test, and deploy a software application. The specific steps and the terminology used may vary depending on the methodology used, but generally, the process includes the following phases:

1. Planning: In this phase, the developers and stakeholders identify the problem or opportunity that the software will address, set goals and objectives, and define the scope and requirements of the project.
2. Analysis and Design: In this phase, the developers analyze the problem, gather information, and create a high-level design for the software. They also identify any potential risks and constraints that may impact the project.
3. Implementation: This phase is also known as the "coding phase," where developers write the code for the software according to the design.
4. Testing: In this phase, the software is tested to ensure that it meets the requirements and is free of bugs and errors. Different types of testing are used, such as unit, integration, system, and acceptance.
5. Deployment: Once the software is tested and validated, it is deployed to a production environment where end users can use it.
6. Maintenance: This phase includes monitoring the software's performance, making updates and bug fixes, and providing technical support to end-users.

3. What are the essential categories of software?

• System program
• Application software
• Embedded software
• Web applications
• Artificial intelligence program
• Scientific software.

4. What are verification and validation?

Verification and validation are two important concepts in software development that ensure that a software application meets its requirements and is free of bugs and errors.

Verification refers to evaluating a software product, service, or system during its development to ensure that it meets the specified requirements and design specifications. Verification activities include reviews, inspections, walkthroughs, and testing. Verification aims to ensure that the software is built correctly and meets the requirements.

Validation refers to evaluating a software product, service, or system at the end of the development process to ensure that it satisfies the business and user needs it was intended to address. Validation activities include testing, usability evaluations, and acceptance testing. Validation aims to ensure that the software is built for the right purpose and meets the users' needs.

5. In what language do you like to write programming algorithms?

Each developer has their own opinions when it comes to programming language choices. However, you should prefer high-level languages because they are dynamic, like C and C++.

6. What are the different SDLC models available?

• waterfall pattern
• spiral pattern
• incremental model
• agile model
• big bang model
• iterative model

7. What is debugging?

Debugging is finding and resolving errors or bugs in a software application. It is an essential part of the software development process, as it helps identify and fix issues that may affect the functionality or performance of the software.

8. What does a software project manager do?

A software project manager is responsible for the planning, execution, and closing of software development projects. They are responsible for the software product's specialization, objectives, structure, and expectations. They also lead planning, backlog care, and stakeholder management and provide the roadmap to create the best software.

9. What are the software prototype and POC?

A software prototype is a preliminary version of a software application used to demonstrate the functionality and design of the final product. It is typically a simplified version of the final product and is not intended to be used in a production environment. The primary purpose of a prototype is to test and validate the design and usability of the software, as well as to gather feedback from users and stakeholders.

A Proof of Concept (POC) demonstrates the feasibility of a concept, idea, or solution. It is a prototype built to prove the concept and demonstrate that it can be done and that it is feasible to develop a final product. A POC is a small-scale and limited version of the final product; its aim to validate the technical feasibility of the proposed solution and to provide a clear understanding of the potential benefits and drawbacks.

10. What is the framework?

A framework is a set of pre-written code, libraries, and tools that provide a structure for developing software applications. It is a reusable set of components developers can use to build software applications more quickly and efficiently. Frameworks are designed to provide a common structure for developers to follow and take care of many of the everyday tasks and functions required for building software applications. Frameworks can be specific to a particular programming language or technology and can be used for different types of software development, such as web development, mobile development, and game development.
