Ques:- What is the difference between Kanban and Scrum, and when would you use each
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.
Ques:- How do you approach Agile at scale (e.g., SAFe, LeSS) for larger teams or organizations
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.
Ques:- What is Scrum, and how do you implement it in software development projects
Right Answer:
Scrum is an Agile framework for managing and completing complex projects.

Implementation involves:

1. **Roles:** Defining roles like Product Owner, Scrum Master, and Development Team.
2. **Sprints:** Working in short, time-boxed iterations (Sprints), typically 2-4 weeks.
3. **Artifacts:** Using artifacts like Product Backlog, Sprint Backlog, and Increment.
4. **Events:** Conducting events such as Sprint Planning, Daily Scrum, Sprint Review, and Sprint Retrospective.
5. **Continuous Improvement:** Regularly inspecting and adapting the process based on feedback.
Ques:- How do you use Sightly (HTL) in component development, and what are its advantages over JSP
Right Answer:
Sightly (HTL) is used in AEM component development as a templating language that separates logic from markup, allowing for cleaner and more maintainable code. Its advantages over JSP include:

1. **Security**: HTL automatically escapes output to prevent XSS attacks.
2. **Simplicity**: It has a simpler syntax that is easier to read and write.
3. **Separation of Concerns**: HTL promotes a clear separation between business logic and presentation.
4. **Performance**: HTL is designed for better performance with built-in caching mechanisms.
5. **Less Boilerplate**: It requires less boilerplate code compared to JSP, making development faster.
Ques:- What is the role of the assembler, linker, and loader in ARM compilation
Right Answer:
The assembler converts assembly language code into machine code (object files). The linker combines object files and resolves references between them to create an executable file. The loader loads the executable into memory and prepares it for execution.
Ques:- What is software refactoring and why is it important
Right Answer:
Software refactoring is the process of restructuring existing computer code without changing its external behavior. It is important because it improves code readability, reduces complexity, enhances maintainability, and helps eliminate technical debt, making future development easier and more efficient.
Ques:- How do you define and manage document workflows in Alfresco
Right Answer:
In Alfresco, document workflows are defined using BPMN 2.0 process definitions. These definitions are managed and deployed via the Alfresco Process Services (APS) engine, often integrated with Alfresco Content Services (ACS). You can use tools like Activiti Designer to create the BPMN definitions, then deploy them to APS. In ACS, users can then initiate these workflows on documents, and tasks are managed through the Alfresco Share interface or custom applications using the Alfresco APIs.
Ques:- How are AUTOSAR configurations handled using tools like DaVinci or EB tresos
Right Answer:
AUTOSAR configurations are handled using tools like DaVinci or EB tresos by providing a graphical interface to define and manage software components, their parameters, and communication settings. These tools allow users to create, modify, and validate the AUTOSAR XML files (ARXML) that describe the system architecture, ensuring compliance with AUTOSAR standards and facilitating integration into the overall software development process.
Ques:- What are the different types of data analysis
Right Answer:
The different types of data analysis are:

1. Descriptive Analysis
2. Diagnostic Analysis
3. Predictive Analysis
4. Prescriptive Analysis
5. Exploratory Analysis
Ques:- What is the purpose of feature engineering in data analysis
Right Answer:
The purpose of feature engineering in data analysis is to create, modify, or select variables (features) that improve the performance of machine learning models by making the data more relevant and informative for the analysis.
Ques:- How do you handle missing data in a dataset
Right Answer:
To handle missing data in a dataset, you can use the following methods:

1. **Remove Rows/Columns**: Delete rows or columns with missing values if they are not significant.
2. **Imputation**: Fill in missing values using techniques like mean, median, mode, or more advanced methods like KNN or regression.
3. **Flagging**: Create a new column to indicate missing values for analysis.
4. **Predictive Modeling**: Use algorithms to predict and fill in missing values based on other data.
5. **Leave as Is**: In some cases, you may choose to leave missing values if they are meaningful for analysis.
Ques:- What are some common data analysis tools and software
Right Answer:
Some common data analysis tools and software include:

1. Microsoft Excel
2. R
3. Python (with libraries like Pandas and NumPy)
4. SQL
5. Tableau
6. Power BI
7. SAS
8. SPSS
9. Google Analytics
10. Apache Spark
Ques:- What is data analysis and why is it important
Right Answer:
Data analysis is the process of inspecting, cleaning, and modeling data to discover useful information, draw conclusions, and support decision-making. It is important because it helps organizations make informed decisions, identify trends, improve efficiency, and solve problems based on data-driven insights.
Ques:- Explain project life cycle?
Right Answer:
The project life cycle consists of five main phases:

1. **Initiation**: Defining the project and obtaining approval.
2. **Planning**: Outlining the project scope, objectives, and creating a roadmap.
3. **Execution**: Implementing the project plan and delivering the project outputs.
4. **Monitoring and Controlling**: Tracking progress and making adjustments as needed.
5. **Closure**: Finalizing all activities, delivering the final product, and closing the project.
Ques:- How will you (as manager) not let your team member leave the company while he’s only there for hike, and your senior management has decided to follow strict budget?
Right Answer:
To retain the team member, I would have an open and honest conversation to understand their motivations and concerns. I would highlight their value to the team, discuss potential career growth opportunities, and explore non-monetary incentives such as professional development, flexible work arrangements, or additional responsibilities that align with their interests. Additionally, I would advocate for their contributions to senior management to seek possible budget adjustments or future salary reviews.
Ques:- What you will do if contractor is not performing work as per drawings and specifications?
Right Answer:
I would first communicate with the contractor to identify the issues and understand their perspective. Then, I would review the drawings and specifications with them to clarify expectations. If the problem persists, I would document the non-compliance, issue a formal notice, and work with the project team to develop a corrective action plan. If necessary, I would escalate the issue to higher management or consider alternative actions as per the contract terms.
Ques:- How should changes controlled?
Right Answer:
Changes should be controlled through a formal change management process that includes documenting the change request, assessing its impact, obtaining necessary approvals, and communicating the changes to all stakeholders.
