Deutsche Bank Interviews

I recently received an interview opportunity at Deutsche Bank for a Java + AWS role with 5+ years of experience. I have completed my B.Tech from a leading engineering institute in Maharashtra and currently work in a product-based environment. Sharing my interview experience below to help anyone preparing for similar roles.

Round 1 – Technical Round (Virtual)

Core Java and Fundamental Concepts: Questions covered OOP principles, design patterns, Spring internals, HashMap implementation, and concurrency concepts. I was also asked about functional programming in Java 8 and immutability.

Coding and DSA

One coding problem based on HashMap (medium difficulty). I was also asked about experience-based discussions on the most challenging project handled end to end.

Round 2 – Technical Round 2 (Virtual)

Medium-level problem: Longest Substring with At Most K Distinct Characters. The round also covered cloud, DevOps, security, Kafka usage, and Java concepts like error vs exception, HTTP methods, and proxies.

Round 3 – F2F Techno-Managerial Round (In Office)

No technical questions as previous round feedback was strong. The discussion focused on career goals, reasons for choosing Deutsche Bank, and key strengths.

Round 4 – HR Discussion (Virtual)

Compensation discussion and policies were covered. I received the offer today after 10 days.

I secured an interview opportunity for a Java Backend Developer - Associate position at Deutsche Bank in Pune through an employee referral. The L1 round was a virtual interview conducted on Microsoft Teams. The interviewer was very polite, patient, and knowledgeable, providing assistance whenever I got stuck. They asked a range of questions covering Java 8 features, functional interfaces, lambda functions, and stream API usage. We also discussed database optimization techniques, handling high-volume events, and optimizing query performance. REST API performance, HTTP status codes, and testing using Junit and Mockito were also part of the discussion. Towards the end, my experience with AWS services and handling production breaks was explored, along with a coding challenge. I was pleased to be selected for the second round, which will be an in-office, face-to-face interview.

There were a total of four rounds in the selection process for the internship. The first round was an Online Assessment that consisted of MCQs (based on core Computer Science subjects) and two coding questions. The remaining three rounds were interviews.

🧠 Online Assessment:
The test consisted of 10 MCQs based on core Computer Science subjects such as OOPs, DBMS, OS, CN, and SQL. Each question carried 4 marks, with no negative marking.

There were 2 coding questions:

Problem 1:

You are given an array and two integers, K and M. There is an operation where any number of elements in the array can be incremented by 1 in a single operation. This operation can be performed at most K times. The goal is to find the maximum number of elements in the array that can be made divisible by M after all operations.

Problem 2:

This was a LeetCode hard-level question based on Sliding Window and Binary Search.

Reference: The question was this one.


Round 1 – Technical Interview (35 min):

• Online round focused on core CS subjects — Data Structures, OOPs in C++, OS, and DBMS.
• No DSA asked. Included 4–5 MCQs and a puzzle.
• Also had resume discussion and a short chat about Cricket.

• Offline round with a friendly and interactive interviewer.
• Focused on situation-based and behavioural questions like team conflicts, handling workload, fraud scenarios, and client issues.
• Also included “Why DB?” and your strengths/weaknesses.

• Focused on behavioral and situational questions — future goals, regrets, mistakes, work pressure, and compensation.
• Ended on a positive and friendly note, with a handshake and mutual excitement about joining Deutsche Bank.

Deutsche Bank visited our campus to hire Summer Interns for tech-analyst roles. The basic shortlist criteria required a CGPA of 4/10 or greater.

Round 1: Coding Round

The first round was a 2.5-hour coding test with two questions and 20 multiple-choice questions. The coding problems were:

1. A slightly modified version of the Trapping Rainwater problem. If I had solved it before, it would have been easy; otherwise, it was a medium-difficulty problem.
2. An easy mathematical problem based on Binary Search, which could also be solved with brute force.

The MCQs were medium to hard difficulty, covering Database Management Systems, Computer Networks, Time Complexities, and Graphs. Out of 200 students, 40 were shortlisted for Round 2.

Round 2: Technical Interview

This round had some irony. Many students before me were asked relatively easy questions on topics like BSTs, Linked Lists, Arrays, and some math puzzles. However, when it was my turn, I was immediately hit with a backtracking question: Find all subsets of array. I also faced a question on finding the Inorder successor in a Binary Tree, which I answered correctly. The interviewer then delved into OOPS concepts, asking about types of inheritance, a brief explanation of each, and the usefulness of inheritance. Finally, I was given a mathematical puzzle, for which I provided a satisfactory solution, though not the best one. I felt a bit low after this round, as I perceived others had performed better. To my surprise, I received a call informing me that I was the first person to be shortlisted for the HR round!

Round 3: HR Interview

The HR interviewers were incredibly friendly. I arrived two minutes late, so I apologized and waited for permission before sitting down. The interviewer's first statement was, "Your resume was one of the most unique that I have come across in my career." I was thrilled, as I had indeed curated a diverse resume with projects in Android and Front-End Development, startup internships, and roles in both my institute's E-Cell and Dance Club. It later became clear that my unique resume played a significant role in my HR round shortlisting, despite my less-than-stellar technical performance. The interviewer asked me about my projects, my motivations behind them, and how they stood out. I did my best to explain them simply. She also asked why I chose Kotlin over Java for Android Development—a question I had prepared for exhaustively! I articulated my points as succinctly as possible. Next, she inquired about my ability to bond with people from different cultures. I explained that I focus on knowledge rather than background, citing challenges I'd worked on with developers globally. Finally, she posed a situation-based question: "What would you choose from? Protecting the security of your company, or leaving it and saving the life of someone?" Having read many interview experiences, I knew this type of question tests composure and critical thinking rather than a single "right" answer. My response was, "I would call/shout for someone to look into either of those. Also, I would make it a point to install a system that would save my work and encrypt it at a button's click." She seemed satisfied. When asked if I had any questions, I inquired about areas for improvement in my profile. She laughed and said, "The comments will keep coming. You are just getting started!" I left the interview feeling very positive. After four hours of intense pressure, the results were declared. Out of 16 finalists, 8 of us were offered a Summer Internship at Deutsche Bank, India.
