Find Interview Questions for Netcentric technologies

Right Answer:
Version control is a system that records changes to files over time, allowing multiple people to collaborate on a project. It is important in software development because it helps track changes, manage code versions, facilitate collaboration, and recover previous versions if needed.

Right Answer:
I stay updated by following industry blogs, subscribing to newsletters, participating in online forums, attending webinars and conferences, taking online courses, and engaging with developer communities on platforms like GitHub and Stack Overflow.

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:
EME (Enterprise Meta>Environment) is a metadata management tool in Ab Initio that stores, manages, and retrieves metadata related to data processing applications. It provides a centralized repository for metadata, allowing users to track data lineage, manage data definitions, and facilitate collaboration among teams by maintaining version control and documentation of data assets.

Right Answer:
The AEM Dispatcher is a caching and load balancing tool for Adobe Experience Manager (AEM) that helps improve performance and scalability. To configure it for caching and load balancing, you need to:

1. **Install the Dispatcher module** on your web server (e.g., Apache or IIS).
2. **Set up the dispatcher configuration file** (dispatcher.any) to define caching rules, such as which content to cache and for how long.
3. **Configure the cache** by specifying the paths to cache and the rules for invalidation.
4. **Set up load balancing** by defining multiple AEM instances in the configuration, allowing the dispatcher to distribute requests among them.
5. **Enable and configure the filters** to control which requests are cached and which are forwarded to AEM.

After making these configurations, restart the web server to apply the changes.

Right Answer:
You can find out the number of arguments passed to a shell script using the special variable `$#`.

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:
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:
Rate limiting in APIs is a technique used to control the number of requests a user can make to an API within a specific time period. It is implemented by setting thresholds (e.g., requests per minute) and using mechanisms like tokens, counters, or IP address tracking to monitor and restrict access when the limit is exceeded.

Right Answer:
A web service is a standardized way of allowing different applications to communicate over the internet using protocols like HTTP. It provides a method for applications to exchange data and perform operations. An API (Application Programming Interface) is a set of rules and tools that allows different software applications to interact with each other. A web service is a type of API that specifically uses web protocols to enable this interaction.

Right Answer:
Agile is an iterative and incremental approach to project management that focuses on collaboration, flexibility, and customer satisfaction. Unlike traditional, sequential (waterfall) methods, Agile embraces change throughout the project lifecycle through short development cycles called sprints.

Right Answer:
I would assess the organization's context, choose a suitable scaling framework like SAFe or LeSS based on needs, implement it incrementally with training and coaching, focusing on value delivery, and continuously inspect and adapt the implementation based on feedback and results.

Right Answer:
* **Listen actively:** Understand their concerns and perspective.
* **Communicate clearly and frequently:** Keep them informed about progress and challenges.
* **Find common ground:** Focus on shared goals and objectives.
* **Be transparent:** Share data and evidence to support decisions.
* **Facilitate collaboration:** Encourage open dialogue and problem-solving.
* **Coach and mentor:** Help team members grow and improve.
* **Escalate when necessary:** Involve a Scrum Master or manager if the situation doesn't improve.

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.
