Deutsche Bank Interview Experience 2020

  • Last Updated : 21 May, 2021

Round 1(Online Test):

  1. It was a string manipulation question. Suppose input was string1, string2, and k seconds. We have to choose every i from 1 to k and shift a character from the string by i index (eg: if i=3 then ‘a’ would be shifted to ‘d’). Each i could be chosen only once. We need to check if we can convert string1 to string2. (20 marks)
    Input:  
    k=3
    string1 = 'abc'
    string2 = 'ddd'
    Output:  
    Yes
  2. Given N, find two numbers with a product greater than or equal to N and with minimum sum.(50 marks)
    Input -15
    Output-8
  3. It was a DFS question where edges representing time, we had to find the total minimum time spent in visiting all vertices, but there was a sequence given in which we can visit vertices. (50 marks)

    Solved by defining a comparator and then sorting the edges.

    I did second question of 50 marks with all test cases passed and in first question I got 12 marks out of 20.So in total, I got 62 marks out of 120.

    Round 2(Technical): 45 minutes

    1. Tell me about yourself.
    2. Tell me your favourite data structure(Linked list for me).
    3. Difference between linked list and array.
    4. Write a program in notepad and share your screen to find if 1st linked list is contained in 2nd linked list or not, if present then print “yes” otherwise “no”.
    5. Write structure of linked list.
    6. Explain the concepts of oops in detail with real-life examples and also tell the difference between procedural programming language and object-oriented programming language.(explain oops concept from starting and explain in detail).
    7. Explain your project in detail like which technology u used and how many  modules are there in ur project ,everything which is related to ur project.and also explain database of ur project, relations between tables.

    Round 3(Technical): 1 hour

    1. What is circular linked list, try to confuse by giving some conditions.
    2. Write a program to insert a element in circular linked list, but the condition is you have to insert the element after getting smaller element from the given element. (After explaining  my approach he was trying to confuse me by adding some more conditions in the question, so don’t be confused listen the conditions carefully and try to modify your code according to the given conditions).
    3. Explain your first project in detail that you have mentioned in your resume, he asked everything like  database of my project, relations between tables in detail, then he starts asking SQL queries (very difficult), he gave some hypothetical tables to me and asked queries on that tables, and trying to confuse me by adding several conditions on the answer of the query.
