Northrop grumman Business Intelligence Interview Questions

In this section, we’ll review the various interview questions that might be asked during a Business Intelligence interview at Northrop Grumman. The interview process is known for being thorough and focused on evaluating candidates based on their skills, knowledge, and problem-solving abilities. Candidates should be prepared to discuss their technical expertise, past experiences, and how they can contribute to the company's goals.

Technical Skills

1. Can you explain the difference between a struct and a class in C++?

Understanding the distinctions between these two fundamental concepts in C++ is crucial for any technical role at Northrop Grumman.

How to Answer

Discuss the key differences, such as default access levels and inheritance, and provide examples of when you would use each.

Example

“A struct in C++ defaults to public access, while a class defaults to private. I would use a struct for simple data structures that require no encapsulation, while a class would be more appropriate for complex data types that require encapsulation and methods.”

2. What are the four main principles of object-oriented programming?

This question assesses your understanding of OOP, which is essential for software development roles.

How to Answer

Briefly define each principle: encapsulation, inheritance, polymorphism, and abstraction, and provide a practical example of each.

Example

“Encapsulation is about bundling data and methods that operate on that data within one unit. Inheritance allows a class to inherit properties from another class, promoting code reuse. Polymorphism enables methods to do different things based on the object it is acting upon. Lastly, abstraction hides complex implementation details and exposes only the necessary parts.”

3. Describe your experience with SQL and how you have used it in past projects.

SQL is a critical skill for Business Intelligence roles, and interviewers will want to know your proficiency.

How to Answer

Discuss specific projects where you utilized SQL, the complexity of the queries you wrote, and how they contributed to the project’s success.

“In my previous role, I used SQL to extract and analyze data from large databases. I wrote complex queries involving joins and subqueries to generate reports that informed strategic decisions, which improved our operational efficiency by 20%.”

4. How do you approach data visualization and reporting?

This question evaluates your ability to present data effectively.

How to Answer

Explain your process for creating visualizations, the tools you use, and how you ensure that the reports are actionable.

Example

“I typically start by understanding the audience and the key metrics they need. I use tools like Tableau and Power BI to create interactive dashboards that highlight trends and insights. I ensure that my reports are clear and actionable by focusing on the most relevant data points.”

5. Can you describe a challenging data analysis problem you faced and how you solved it?

This question assesses your problem-solving skills and analytical thinking.

How to Answer

Provide a specific example, detailing the problem, your analysis process, and the outcome.

Example

“I once faced a challenge where our sales data was inconsistent across different regions. I conducted a thorough analysis to identify discrepancies, which involved cleaning the data and standardizing formats. After resolving the issues, I implemented a new data validation process that reduced errors by 30%.”

Behavioral Questions

1. Tell me about a time you had a conflict with a teammate. How did you handle it?

This question evaluates your interpersonal skills and ability to work in a team.

How to Answer

Use the STAR method (Situation, Task, Action, Result) to structure your response.

Example

“In a previous project, I had a conflict with a teammate over the direction of our analysis. I initiated a one-on-one discussion to understand their perspective and shared my concerns. We ultimately found a compromise that combined our ideas, leading to a more robust analysis and a successful project outcome.”

4. How do you prioritize your work when you have multiple deadlines?

This question assesses your time management skills.

How to Answer

Discuss your approach to prioritization, including any tools or methods you use.

Example

“I prioritize my work by assessing deadlines and the impact of each task. I use project management tools like Trello to keep track of my tasks and deadlines. I focus on high-impact tasks first and regularly communicate with my team to ensure alignment on priorities.”

This question evaluates your self-awareness and honesty.

How to Answer

Choose a strength that is relevant to the role and a weakness that you are actively working to improve.
