Find Interview Questions for Coriolis Technologies

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:
The different types of APIs are:

1. **Open APIs (Public APIs)** - Available to developers and third parties.
2. **Internal APIs (Private APIs)** - Used within an organization.
3. **Partner APIs** - Shared with specific business partners.
4. **Composite APIs** - Combine multiple endpoints into a single call.
5. **Web APIs** - Accessible over the internet using HTTP/HTTPS.

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:
HTTP methods are standardized request types used in APIs to perform actions on resources. The main methods are:

1. **GET**: Retrieve data from a server.
2. **POST**: Send data to a server to create a new resource.
3. **PUT**: Update an existing resource on the server.
4. **DELETE**: Remove a resource from the server.
5. **PATCH**: Apply partial modifications to a resource.

These methods define the action to be performed on the specified resource in the API.

Right Answer:
OAuth is an open standard for access delegation commonly used for token-based authentication and authorization. It allows third-party applications to access a user's resources without sharing their credentials.

In API authentication, OAuth works by having the user authorize the application to access their data. The process involves:

1. The user is redirected to an authorization server to log in and grant permission.
2. The authorization server issues an access token to the application.
3. The application uses this access token to make API requests on behalf of the user.
4. The API validates the token and grants access to the requested resources.

Right Answer:
Commonly used compiler flags for ARM compilation include:

1. `-mcpu=<cpu-type>`: Specify the target ARM CPU architecture.
2. `-mthumb`: Generate Thumb code.
3. `-mfpu=<fpu-type>`: Specify the floating-point unit.
4. `-mfloat-abi=<abi-type>`: Define the floating-point ABI.
5. `-O<n>`: Set optimization level (e.g., `-O0`, `-O1`, `-O2`, `-O3`).
6. `-g`: Include debug information.
7. `-Wall`: Enable all compiler warnings.
8. `-Werror`: Treat warnings as errors.
9. `-D<macro>`: Define a macro.
10. `-I<directory>`: Add a directory to the include path.

Right Answer:
For configuration and integration in AUTOSAR, I use tools like Vector DaVinci Configurator, Elektrobit Tresos, and Arccore Arctic Studio.

Right Answer:
Memory regions in ARM compilation are defined and managed using linker scripts or scatter files. These files specify the layout of memory, including the start and end addresses of different sections (like code, data, and stack) and how they should be placed in the available memory. The ARM compiler and linker use this information to organize the program's memory allocation during the build process.

Right Answer:
AUTOSAR supports reusability and scalability through its standardized architecture, which allows software components to be developed independently and reused across different projects. It defines clear interfaces and communication protocols, enabling components to be easily integrated. Additionally, the layered architecture separates application software from hardware, allowing for scalability as new features or hardware platforms can be added without significant changes to existing components.

Right Answer:
Common tools used in AUTOSAR development include:

1. AUTOSAR Builder
2. Vector DaVinci Developer
3. ETAS ISOLAR-A
4. Elektrobit EB tresos
5. Arccore Arxml Editor
6. MATLAB/Simulink with AUTOSAR toolboxes
7. CANoe for testing and validation

Right Answer:
The Agile Manifesto values:

* **Individuals and interactions** over processes and tools.
* **Working software** over comprehensive documentation.
* **Customer collaboration** over contract negotiation.
* **Responding to change** over following a plan.

That is, while the items on the right have value, we value the items on the left more.

Right Answer:
Success in Agile is measured by:

* **Output:** Delivering valuable, working software frequently; achieving the product vision; meeting business goals; customer satisfaction; and predictability (consistent delivery).
* **Team Health:** Team morale; continuous improvement (velocity trends, retrospectives leading to action); collaboration; self-organization; and sustainable pace.

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:
We ensure consistent Agile processes through:

* **Training and coaching:** Ensuring the team understands Agile principles and practices.
* **Regular audits and retrospectives:** Identifying deviations and areas for improvement.
* **Using tools and templates:** Standardizing processes and providing guidelines.
* **Defining clear roles and responsibilities:** Ensuring everyone knows their part in the process.
* **Promoting open communication and feedback:** Encouraging early detection of issues.

Right Answer:
Contract administration involves managing and overseeing the execution of a contract to ensure that all parties fulfill their obligations, maintain compliance with terms, and address any issues that arise during the contract's lifecycle.

Right Answer:
Onsite projects are those where the work is done at the client's location, while offshore projects are conducted at a different location, often in another country, typically to take advantage of cost savings or specialized skills.

Right Answer:
I am seeking new challenges and opportunities for growth that align better with my career goals.

Right Answer:
Yes, I agree. Forming a team, developing the team, and improving knowledge are key responsibilities of a project manager.

Right Answer:
Risk impact refers to the potential effect or consequence of a risk on a project if it occurs, while risk probability is the likelihood or chance that the risk will actually happen.
