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

• Write a function to determine if two strings are anagrams of each other. Given two strings, write a function to return True if the strings are anagrams of each other and False if they are not. Note: A word is not an anagram of itself.

• Create a function to check if a string is a palindrome. Given a string, write a function to determine if it is a palindrome or not. A palindrome is a word/string that reads the same way forward as it does backward.

• How would you provide rejected loan applicants with reasons for rejection without access to feature weights? Suppose you have a binary classification model that determines loan eligibility. As a financial company, you must provide each rejected applicant with a reason for their rejection. Given that you don't have access to the feature weights, how would you generate these reasons?

• Are we overestimating or underestimating the actual population’s credit score using a fixed cutoff? Assume you have a credit model with a calibrated score for creditworthiness, with a small margin of error. If the model estimates a score of 83%, the actual score likely falls between 81% and 85%. By using 83% as a cutoff for creditworthiness, are we overestimating or underestimating the actual credit scores of the population?

• How would you design an ML system to extract, transform, and store data from Reddit and Bloomberg APIs? As a machine learning engineer for a large bank, you have access to the Reddit API for finance and news-related subreddits and the Bloomberg API for daily stock prices. How would you design an ML system that extracts data from these APIs, transforms it, and stores it in a format usable by downstream modeling teams?
