Deutsche Bank interview questions

The first stage of the interview was supposed to be a technical interview using Visual Studio. However, during the interview, they sent me a link to an online coding environment. I wasn’t familiar with this platform, and it didn’t have autocompletion, which made coding difficult and added to my stress, especially since I hadn’t had the chance to prepare in advance. There were two interviewers present, each asking questions in turn. As a developer with several years of experience, I felt that this type of coding challenge, with constant questions and a stressful setup, is not ideal for assessing programming skills.

Round 1 (Online test): There is total three questions. Round 2 (Tech-1 45 min): Tell me about yourself. I did internship so he wants from me to share my internship experience, technologies that was used during my internship. (Approx. 20 to 25 min). I used protocols in my intern so he asked me about some protocols. He asked me in which data Structure I m comfortable so I told him “LINKED LIST”, so he asked me to how I create linked list, how to insert, delete, traverse etc. He didn’t ask me in depth. After this he asked me about my project (I have only one major project and 2nd is normal like minor) that how much you take to complete, what are the tasks and how you completed them by any one help, or google or yourself. (Approx. 5-7 min) Again, he come to networking and asked me about some application protocols, that was not included in my internship. Round 3 (Tech-2 90 min): Tell me about yourself. This round start with DSA, they give me 4-5 questions (2-3 situation are given with each question) (45-50 min) Each letter denote a number [a-1, b-2,……,z=26] so you have k and N, where k is sum if number and N is length of string that you need to create, ex: – K=42, N=5 then string will be aaamz(1+1+1+13+26), You need to find lexicological smaller string Convert number in single digit by adding digits of number until get single digit Check string 2 is rotation of string 1 or not. Rotten orange problem (you can find this either on GFG or LeetCode) Difference between CPP and JAVA. Difference between overloading and overriding String Buffer and string Builder He asked me about some other concepts from java (Here he wants to go in depth but I told him that I just familiar with java OOPs concept or core part). How HashMap works Are pointers are used in java? Now he comes to OS, what is deadlock, how to remove it (Here I forget the name of algo so he helps me to remind it) how to prevent deadlock. Now he comes to DBMS, what is Distributed System What type of architecture you used in your project? He asked me to write query to find a record who has 2nd highest salary (this question is trending now a days, so please learn about this there are three ways) This question is for one of my internship technology. In last he asked me a puzzle where suppose I have 10 balls of same weight except one ball, now how I found that ball that is lighter in weight than other 9 balls (here you can use binary search approach) Any question that you want to ask from us?
