Top Accenture Data Analyst Interview Questions and Answers

1. What is OOPS?

• OOPS stands for Object-Oriented Programming System. It is a programming paradigm based on the concept of objects which contain data and methods.

2. 4 Pillars of OOPS?

• Encapsulation: Bundling data and methods that operate on the data into a single unit, or class.
• Inheritance: A mechanism where one class can inherit properties and methods from another class.
• Polymorphism: The ability of different objects to be accessed through the same interface, allowing for different implementations.
• Abstraction: Hiding the complex implementation details and showing only the necessary features of an object.

3. What is Polymorphism?

• Polymorphism allows objects of different classes to be treated as objects of a common superclass. It enables a single interface to represent different underlying forms (data types).

4. Code: Sort an array in either ascending or descending order.

• Here’s a simple Python code snippet to sort an array:

  def sort_array(arr, order=’ascending’):
  if order == ‘ascending’:
  return sorted(arr)
  elif order == ‘descending’:
  return sorted(arr, reverse=True)
  else:
  return arr

  # Example usage
  array = [5, 2, 9, 1, 5, 6] print(“Ascending:”, sort_array(array, ‘ascending’))
  print(“Descending:”, sort_array(array, ‘descending’))

• Ascending order: Uses sorted(arr) to sort the array in ascending order.
• Descending order: Uses sorted(arr, reverse=True) to sort the array in descending order.

5. What are time shift timings?

• Time shifting in data analysis refers to adjusting the time series data to align different time periods for comparison, analysis, or forecasting. Here are some common time shift techniques:

1. Lagging:
   • Shifting data backward in time.
   • Used to compare current data with past values.
2. Leading:
   • Shifting data forward in time.
   • Used to compare current data with future values.
3. Rolling Windows:
   • Applying a function (e.g., average, sum) over a sliding window of time periods.
   • Used for smoothing data or identifying trends.
4. Seasonal Adjustment:
   • Removing seasonal effects to reveal underlying trends.
   • Common in economic and financial data analysis.
5. Aligning Time Zones:
   • Adjusting data to a common time zone.
   • Important for global datasets with different time zones.
6. Resampling:
   • Changing the frequency of time series data (e.g., daily to monthly).
   • Used to aggregate or disaggregate data for analysis.

These techniques help in analyzing temporal patterns, identifying trends, and making accurate predictions.

6. What is a primary key?

• A primary key is a unique identifier for each record in a database table. It ensures that each entry is distinct and helps establish relationships between different tables.

7. What is the difference between a clustered and a non-clustered index?

• Clustered Index: Sorts and stores data rows based on key values.
• Non-Clustered Index: Creates a separate structure with pointers to data rows.

8. Explain the concept of normalization in databases.

• Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity. It involves dividing a database into two or more tables and defining relationships between them.

9. What is a JOIN in SQL? Name different types of JOINs.

• Combines rows from two or more tables based on related columns.
• Types: INNER JOIN, LEFT JOIN, RIGHT JOIN, FULL OUTER JOIN.

10. How do you handle missing data in a dataset?

• Missing data can be handled by removing rows or columns with missing values, replacing them with statistical measures (mean, median, mode), or using algorithms that support missing values.

11. What is a pivot table, and how do you use it?

• A pivot table is a data summarization tool that is used to automatically sort, count, and total data stored in a table and present it in a new table. It’s commonly used for data analysis in Excel.

12. Explain the concept of data cleaning.

• Data cleaning involves identifying and correcting (or removing) errors and inconsistencies in data to improve its quality. It includes tasks like handling missing values, correcting data types, and removing duplicates.

13. What is a regression analysis?

• Regression analysis is a statistical method used to examine the relationship between two or more variables. It helps in predicting the value of a dependent variable based on one or more independent variables.

14. What is the difference between supervised and unsupervised learning?

• Supervised learning uses labeled data to train models, while unsupervised learning uses unlabeled data to identify patterns and relationships in the data.

15. What are outliers, and how do you detect them?

• Outliers are data points that are significantly different from other observations. They can be detected using statistical methods like Z-scores, IQR (Interquartile Range), and visual methods like box plots.

16. Explain the concept of a data warehouse.

• A data warehouse is a central repository of integrated data from multiple sources. It stores current and historical data and is used for creating analytical reports and data analysis.

17. What is ETL?

• ETL stands for Extract, Transform, Load. It refers to the process of extracting data from different sources, transforming it into a suitable format, and loading it into a data warehouse or database.

18. How do you ensure data quality?

• Ensuring data quality involves validating data accuracy, consistency, completeness, reliability, and timeliness. This can be achieved through data cleaning, data profiling, and regular audits.

19. What is a time series analysis?

• Time series analysis involves analyzing data points collected or recorded at specific time intervals. It is used to identify trends, seasonal patterns, and cyclic behaviors in data.

20. Explain the use of Python/R in data analysis.

• Python and R are programming languages widely used in data analysis. They offer libraries and packages for data manipulation (Pandas, dplyr), visualization (Matplotlib, ggplot2), and statistical analysis (SciPy, stats).
