O&m Engineer - Planning/ Project Controller Project Management

Ques:- What is dirac delta function and its fourier transform andits importance?

Asked In :- Protege Solutions, Radicle Software, Bhanguz, Target Integration, FYERS Securities, CHIPSY, INFOMAZE, SOFTWAREGEN TECHNOLOGIES, Sysfore Technologies, TechEra IT Consulting,

Right Answer:
The Dirac delta function is a mathematical function that represents an idealized point mass or point charge, characterized by being zero everywhere except at a single point, where it is infinitely high, and integrates to one. Its Fourier transform is a constant function, meaning that it has equal amplitude across all frequencies. The importance of the Dirac delta function lies in its ability to simplify the analysis of systems in physics and engineering, particularly in signal processing and control systems, as it allows for the representation of impulses and point sources.

Right Answer:
To debug a failed graph in a production environment, follow these steps:

1. **Check Logs**: Review the error logs generated by the graph for any specific error messages.
2. **Identify the Failure Point**: Determine which component or transformation caused the failure by analyzing the logs and the graph's execution flow.
3. **Validate Input Data**: Ensure that the input data is in the expected format and does not contain any anomalies.
4. **Run in Debug Mode**: If possible, run the graph in debug mode to step through the execution and observe the behavior of each component.
5. **Check Environment Variables**: Verify that all necessary environment variables and configurations are correctly set.

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.

Software Development

Ques:- What is microservices architecture and how does it differ from monolithic architecture

Asked In :- mobifly, HashRoot Technologies, AgilePoint Software India, Direction Software Solutions, Pluribus Networks India, Envision Enterprise Solutions, Estuate, G7 CR Technologies, Knowledge Splice, Microland,

Right Answer:
Microservices architecture is a software design approach where an application is built as a collection of small, independent services that communicate over APIs. Each service is responsible for a specific function and can be developed, deployed, and scaled independently.

In contrast, monolithic architecture is a traditional approach where an application is built as a single, unified unit. All components are tightly integrated and run as one process, making it harder to scale and update individual parts without affecting the whole system.

Agile

Ques:- What is the difference between a user story, a task, and an epic in Agile

Asked In :- Vinove Software & Services Pvt Ltd, Object Frontier Software, Netaxis IT Solutions (p), Queppelin Technology Solutions, Walkover Web Solutions, STIC SOFT E-SOLUTIONS, Chegg India, Indocosmo Systems, Priya Softweb Solutions, Spadeworx Software Services,

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.

Agile

Agile

Ques:- Can you describe a time when an Agile project didn’t go as planned and how you handled it

Asked In :- Xoriant Solutions Pvt Ltd, KRIOS Info Solutions, Netaxis IT Solutions (p), Trigent Software, Fortunesoft IT Innovations, Born Commerce, TNQ Technologies, LiteBreeze Infotech, Oodles Technologies, Sun Technology Integrators,

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."

Asked In :- Fluid AI, Trigent Software, Itobuz Technologies, RANDSTAD INDIA PVT, GOQii Technologies, Dhruvsoft Services, Radicle Software, Webvillee Technology, Fission Infotech, Noesys Consulting,

Right Answer:
Outliers are data points that significantly differ from the rest of the dataset. They can skew results and affect statistical analyses. To handle outliers, you can:

1. Identify them using methods like the IQR (Interquartile Range) or Z-scores.
2. Remove them if they are errors or irrelevant.
3. Transform them using techniques like log transformation.
4. Use robust statistical methods that are less affected by outliers.
5. Analyze them separately if they provide valuable insights.
