6. Write a query to get the last transaction for each day from a transaction table.
Ans: This question will assess your ability to use the window functions to solve these queries. You can approach this answer with a simple example based on SQL queries.
| SELECT id, transaction_value, created_at FROM ( SELECT *, ROW_NUMBER() OVER (PARTITION BY DATE(created_at) ORDER BY created_at DESC) as rn FROM transactions ) t WHERE rn = 1; |
| WITH first_purchase AS ( SELECT user_id, MIN(purchase_date) as first_date FROM purchases GROUP BY user_id ) SELECT COUNT(DISTINCT p.user_id) FROM purchases p JOIN first_purchase fp ON p.user_id = fp.user_id WHERE p.purchase_date > fp.first_date; |
| SELECT employee_id, salary FROM ( SELECT *, ROW_NUMBER() OVER (PARTITION BY employee_id ORDER BY entry_date DESC) as rn FROM payroll ) p WHERE rn = 1 |
10. How would you handle missing data in a dataset using Python?
Ans: For handling missing data you can use Python Panda library which can help you in identifying missing values and also replacing it with a proper value. You can reply with the following in these type of Amazon business intelligence interview questions. I would use pandas to identify missing values and decide on imputation strategies based on the data context. For numerical data, I might fill missing values with the mean or median. 11. How would you ingest near real-time JSON data and optimize read/write operations? Ans: You can answer this question with the Apache Kafka you can perform real time data ingestion and store the data in Amazon DynamoDB for low latency access. If you implement proper partitioning and indexing it would optimise read and write operations. 12. How would you analyze a noisy and volatile dataset? Ans: You can perform exploratory data analysis to identify the patterns and outliers in the dataset. This technique like moving averages, consulting domain experts can help you in understanding and mitigating the noise factors effectively in the dataset. 13. How would you simulate overlapping job schedules to estimate annual costs due to failures? These types of Amazon business intelligence interview questions evaluates your ability to model and simulate scenarios. You can answer this question with the Python function: you can simulate random start times for two jobs each night and check for any overlaps. By running the simulation for over 365 days you can count the number of overlaps. To calculate cost you can multiply by the number of failures by the cost failure. 14. How would you measure the success of a new feature on Amazon’s product page? Ans: You can answer this question by mentioning metrics like conversion rates, click through rates, overall sales, and more. You can use different testing such as A/B Test to compare the new feature group to a control group. We will also consider using secondary KPIs such as session duration, bounce rate, and more to detect any unexpected behavior from the user's side. 15. How do you differentiate between correlation and causation in business data? Ans: Correlation shows a relationship between two variables, but it is not necessarily that one causes the other. To determine causation, you would rely on controlled experiments like A/B testing or causal inference methods like regression discontinuity or instrumental variables when experiments aren’t feasible. 16. Tell me about a time you used data to influence a major decision. Ans: You can mention your past experience to answer these types of Amazon business intelligence interview questions. Consider a situation when the sale was declining in your company. At my previous job, our sales were declining in one region. I analyzed customer churn data and discovered delivery delays were causing dissatisfaction. I presented the findings to leadership, who invested in local warehousing. We saw a 25% reduction in churn the following quarter. 17. Describe a time when you made a mistake in your analysis and how you handled it? Ans: In this type of Amazon business intelligence interview questions you will need to present a practical experience in your previous companies. Tell if you faced any such issue or let them know if you did not and give them a valid reason along with it. 18. How would you identify duplicate records in a large CSV file using Python? Ans: We can use the Python Pandas file and use duplicated() method to find the duplicate rows in data. For large data you can chunksize the data to read the file in the parts and store hash keys in a set for duplicate detection. It ensures the efficient use of memory. This type of amazon business intelligence interview questions are important using Python.| import pandas as pd df = pd.read_csv('file.csv') duplicates = df[df.duplicated()] |
19. How would you handle missing data in a dataset using Python?
Ans: You can handle missing data and formats using the pd.to_datetimne() with errors = ‘coerce’ to convert the inconsistent formats and drop the input.
