Find Interview Questions for Aviasales

Right Answer:
GET is used to retrieve data from a server, POST is used to send data to a server to create a resource, PUT is used to update an existing resource on the server, and DELETE is used to remove a resource from the server.

Right Answer:
RESTful principles include:

1. **Statelessness**: Each API call must contain all the information needed to understand and process the request, with no stored context on the server.
2. **Client-Server Architecture**: The client and server are separate, allowing for independent development and scalability.
3. **Uniform Interface**: A consistent way to interact with resources, typically using standard HTTP methods (GET, POST, PUT, DELETE).
4. **Resource-Based**: APIs should expose resources (data entities) through URIs, and clients interact with these resources.
5. **Representation**: Resources can be represented in various formats (like JSON or XML), and clients can request the format they prefer.
6. **Cacheability**: Responses should indicate whether they can be cached to improve performance and reduce server load.

These principles guide the design of APIs to be scalable, efficient, and easy to use.

Right Answer:
API versioning is the practice of managing changes to an API by assigning version numbers to different iterations of the API. It is important because it allows developers to introduce new features or make changes without breaking existing client applications that rely on older versions, ensuring backward compatibility and a smoother transition for users.

Right Answer:
The common status codes in HTTP responses are:

- **200**: OK
- **201**: Created
- **204**: No Content
- **400**: Bad Request
- **401**: Unauthorized
- **403**: Forbidden
- **404**: Not Found
- **500**: Internal Server Error
- **502**: Bad Gateway
- **503**: Service Unavailable

Right Answer:
JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. In APIs, JSON is commonly used to format data exchanged between a client and a server, allowing for structured data representation in requests and responses.

Right Answer:
To use inline assembly in ARM C code, you can use the `asm` keyword followed by the assembly instructions in a string. For example:

```c
asm("MOV R0, #1");
```

You can also use the extended syntax for more complex operations:

```c
asm volatile (
"MOV R0, #1n"
"ADD R1, R0, #2"
);
```

Make sure to include any necessary input and output operands if needed.

Right Answer:
RESTful APIs are web services that follow the principles of Representational State Transfer (REST). They use standard HTTP methods (GET, POST, PUT, DELETE) to perform operations on resources identified by URLs. To implement RESTful APIs in software projects, you typically:

1. Define the resources and their representations (e.g., JSON or XML).
2. Use HTTP methods to create, read, update, and delete these resources.
3. Set up routing in your server to handle requests and responses.
4. Ensure stateless communication, meaning each request from a client contains all the information needed to process it.
5. Optionally, implement authentication and authorization for secure access.

Right Answer:

Right Answer:
Error handling in the RTE (Runtime Environment) is managed through the use of error detection mechanisms, such as error hooks and status codes. The RTE provides interfaces for reporting errors, which can be handled by the application software components or the underlying operating system. Additionally, the RTE can log errors and trigger appropriate responses based on the severity of the error, ensuring that the system can recover or safely shut down if necessary.

Right Answer:
The RTE (Runtime Environment) handles client-server communication by using a defined interface that allows client applications to request services from server applications. It manages the communication through the use of ports, where the client sends requests via a request port and the server responds through a response port. The RTE ensures that the data is correctly marshaled and unmarshaled between the client and server, facilitating seamless interaction while adhering to the AUTOSAR standards.

Right Answer:
The Scrum Master is a servant-leader who helps the Scrum Team follow the Scrum framework. They facilitate Scrum events (Sprint Planning, Daily Scrum, Sprint Review, Sprint Retrospective), remove impediments, protect the team from distractions, and coach the team on Agile principles and practices.

Right Answer:
To facilitate effective sprint retrospectives, I would:

1. **Set the Stage:** Create a safe and open environment where the team feels comfortable sharing.
2. **Gather Data:** Collect information about what went well, what didn't, and any challenges faced during the sprint.
3. **Generate Insights:** Facilitate a discussion to identify root causes and patterns.
4. **Decide on Actions:** Collaborate to define specific, actionable, measurable, achievable, relevant, and time-bound (SMART) improvements.

6. **Follow Up:** Track progress on action items in subsequent sprints to ensure continuous improvement.

Right Answer:
"In one project, we underestimated the complexity of integrating a new third-party API. This caused us to miss our sprint goal. To address this, we immediately re-estimated the remaining work, broke down the integration into smaller, more manageable tasks, and increased communication with the API vendor. We also temporarily shifted team focus to prioritize the integration, delaying a lower-priority feature for the next sprint. Finally, in the sprint retrospective, we implemented a better vetting process for third-party integrations to avoid similar issues in the future."

Right Answer:
* **Clear Sprint Goals:** Define specific, measurable, achievable, relevant, and time-bound (SMART) goals for each iteration.
* **Daily Stand-ups:** Facilitate short, focused daily meetings to identify roadblocks and coordinate efforts.
* **Sprint Backlog Management:** Keep the sprint backlog refined, prioritized, and realistic based on team capacity.
* **Timeboxing:** Adhere to time limits for meetings and tasks to prevent scope creep and maintain momentum.
* **Focus on Value:** Prioritize tasks that deliver the most business value within the iteration.
* **Remove Impediments:** Proactively identify and resolve obstacles that hinder the team's progress.
* **Limit Work in Progress (WIP):** Encourage the team to focus on completing tasks before starting new ones.
* **Continuous Feedback:** Regularly review progress, gather feedback, and adapt plans as needed.
* **Defined "Definition of Done":** Ensure a clear understanding of what it means for a task to be considered complete.
* **Team Collaboration & Communication:** Foster open and effective communication and collaboration within the team.
