Example questions could include:

1. “Describe a project that you have worked on.”
2. “What are your strengths and weaknesses?”

HR Round

The final stage is an HR round where behavioral and situational questions will be asked. The HR team will be keen to understand what you can bring to the company and how you align with the company culture. Questions in this round could include:

2. “What did you do when you were under immense pressure to solve an issue?”
3. “How will you react when somebody disagrees with you?”

Approval Letter

If you successfully navigate through all these rounds, you will receive an approval letter confirming your selection for the Data Analyst position at Caterpillar.

Typically, interviews at Caterpillar vary by role and team, but commonly, Data Analyst interviews follow a fairly standardized process across these question topics.

1. Create a function combinational_dice_rolls to list all possible combinations of dice rolls.

Given n dice each with m faces, write a function combinational_dice_rolls to dump all possible combinations of dice rolls. Bonus: Can you do it recursively?

2. Develop a function is_subsequence to check if one string is a subsequence of another.

Given two strings, string1 and string2, write a function is_subsequence to find out if string1 is a subsequence of string2.

3. Write a function to return all prime numbers up to a given integer N.

Given an integer N, write a function that returns a list of all of the prime numbers up to N. Return an empty list if there are no prime numbers less than or equal to N.

4. Create a function to add the frequency of each character in a string after each character.

Given a string sentence, return the same string with an addendum after each character of the number of occurrences a character appeared in the sentence. Do not treat spaces as characters and exclude characters in the discard_list.

5. Write a function sorting to sort a list of strings in ascending alphabetical order from scratch.

Given a list of strings, write a function sorting to sort the list in ascending alphabetical order without using the built-in sorted function. Return the new sorted list rather than modifying the list in place. Bonus: Aim for a solution with (O(n \log n)) complexity.

6. What factors could have biased Jetco’s fastest average boarding times result?

Jetco had the fastest average boarding times in a study. Identify potential biases in the study and what factors you would investigate to validate the result.

7. How would you ensure data quality across different ETL platforms for PayPal’s Southern African survey data?

10. How would you evaluate whether using a decision tree algorithm is the correct model for predicting loan repayment?

You are tasked with building a decision tree model to predict if a borrower will pay back a personal loan. How would you evaluate if a decision tree is the right choice? Additionally, how would you evaluate the model’s performance before and after deployment?

11. What are the key differences between classification models and regression models?

Explain the primary differences between classification models and regression models in machine learning.

12. When would you use a bagging algorithm versus a boosting algorithm?

Compare two machine learning algorithms. In which scenarios would you prefer a bagging algorithm over a boosting algorithm? Provide examples of the tradeoffs between the two.

13. How would you determine if you have enough data to create an accurate ETA prediction model?

You have 1 million app rider journey trips in Seattle and want to build a model to predict ETA after a ride request. How would you assess if the data is sufficient for an accurate model?

14. How would you explain what a p-value is to someone who is not technical?

Explain the concept of a p-value in simple terms to someone without a technical background.

15. What is the probability that a red marble was pulled from Bucket #1?

Given two buckets with different distributions of red and black marbles, calculate the probability that a red marble was pulled from Bucket #1.

16. What is the probability that Amy wins the game by rolling a 6 first?

Amy and Brad take turns rolling a fair six-sided die, with Amy starting first. Calculate the probability that Amy wins by rolling a 6 before Brad.
