Find Interview Questions for Atlassian

Right Answer:
We prioritize features or tasks in an Agile sprint using a combination of factors like business value, risk, effort/size, dependencies, and urgency. Product Owner usually leads this, using techniques like MoSCoW (Must have, Should have, Could have, Won't have) or story pointing, to ensure the most valuable items are tackled first.

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.
5. **Close the Retrospective:** Summarize action items and assign owners.
6. **Follow Up:** Track progress on action items in subsequent sprints to ensure continuous improvement.

Right Answer:
* **Epic:** A large, high-level user story that is too big to complete in a single iteration. It's usually broken down into smaller user stories.
* **User Story:** A small, self-contained requirement that represents a valuable piece of functionality for the end-user. It follows the format: "As a [user type], I want [goal] so that [benefit]".
* **Task:** A small, actionable item that needs to be done to complete a user story. It's a technical breakdown of the work required by the development team.

Right Answer:
A product backlog is a prioritized list of features, bug fixes, tasks, and requirements needed to build a product. It's managed through regular refinement, prioritization, estimation, and updates based on feedback and changing business needs, often facilitated by the Product Owner.

Right Answer:
Kanban focuses on visualizing workflow, limiting work in progress (WIP), and continuous flow. Scrum uses time-boxed iterations (sprints) with specific roles (Scrum Master, Product Owner, Development Team) and events (sprint planning, daily scrum, sprint review, sprint retrospective).

Use Kanban when you need continuous delivery, have evolving priorities, and want to improve workflow incrementally. Use Scrum when you need structured development with fixed-length iterations, have clear goals for each iteration, and benefit from team collaboration with defined roles.

Right Answer:
An ALV (ABAP List Viewer) report is a tool in SAP that allows for the display of data in a structured and interactive format. To create an ALV report in ABAP, follow these steps:

1. Use the function module `REUSE_ALV_GRID_DISPLAY` or `REUSE_ALV_LIST_DISPLAY`.
2. Define the data structure and internal table to hold the data.
3. Populate the internal table with data from the database.
4. Define field catalog for column headers and attributes.
5. Call the ALV function module, passing the internal table and field catalog as parameters.

This will generate an interactive report with sorting, filtering, and layout options.

Right Answer:
The main layers of the AUTOSAR architecture are:

1. Application Layer
2. Runtime Environment (RTE)
3. Basic Software (BSW) Layer
4. Microcontroller Abstraction Layer (MCAL)

Right Answer:
Startup files in an ARM environment are assembly or C source files that initialize the system before the main program runs. They typically set up the stack pointer, initialize global variables, and call the main function. These files ensure that the hardware and software environment is correctly configured for the application to run.

Right Answer:
To integrate third-party BSW modules into the AUTOSAR stack, I follow these steps:

1. **Compatibility Assessment**: Verify that the third-party module is compliant with the AUTOSAR standards and the specific version being used.

2. **Interface Definition**: Review and understand the interfaces of the third-party module to ensure they align with the AUTOSAR architecture.

3. **Configuration**: Configure the BSW module using the AUTOSAR tools to match the system requirements and ensure proper communication with other components.

4. **Integration Testing**: Conduct integration tests to validate the functionality and performance of the third-party module within the AUTOSAR environment.

5. **Documentation**: Maintain thorough documentation of the integration process, including any modifications made and the configuration settings used.

6. **Continuous Monitoring**: After integration, monitor the module's performance and compatibility during system operation to address any issues that may arise.

Right Answer:
In AEM, content is stored in the Java Content Repository (JCR) using a hierarchical structure of nodes and properties. Each piece of content is represented as a node, which can have child nodes and properties that store data. To retrieve content, AEM uses the JCR API, allowing developers to query the repository using SQL2 or XPath queries, or by navigating the node structure programmatically.

Right Answer:
An API endpoint is a specific URL or URI where an API can be accessed by a client to perform operations like retrieving or sending data. It defines the location and method (such as GET, POST) for interacting with the API.

Right Answer:
API authentication is the process of verifying the identity of a user or application trying to access an API. Common methods include:

1. **API Keys**: Unique keys provided to users to access the API.
2. **Basic Authentication**: Uses a username and password encoded in Base64.
3. **OAuth**: A token-based authentication method that allows users to grant limited access to their resources without sharing credentials.
4. **JWT (JSON Web Tokens)**: A compact, URL-safe means of representing claims to be transferred between two parties, often used for stateless authentication.
5. **HMAC (Hash-based Message Authentication Code)**: Uses a secret key to create a hash of the request, ensuring data integrity and authenticity.

Right Answer:
Synchronous API calls wait for the response before moving on to the next task, while asynchronous API calls allow the program to continue executing other tasks while waiting for the response.

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:
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.
