Deutsche Bank On-Campus Interview Experience for FTE 2020(Virtual).
Deutsche Bank recently visited our campus (Cummins College of Engineering for Women, Pune) for hiring graduate analysts and interns.
Online test was conducted on HackerEarth and face to face rounds on Skype. Criteria for online was 7 CGPA.

Round 1: (Online Test, 90 mins)
It consisted 3 coding questions (for 120 points).
1st was based on String Manipulation (20 points)
I don’t remember 2nd (50 points), 3rd was modification of Longest Increasing Subsequence (50 points).
I was able to solve 11/14 testcases for 1st and 13/15 testcases for 3rd.
Around 350 students appeared for the test, 28 students were selected for next round.
Tip: Constraints given are high so brute force may pass partial test cases but you need optimized solution to pass all the test cases.

Round 2: (Technical Round, 45-50 mins)
Introduce yourself.
Interviewer asked me favourite 4 subjects, and said he will interview me on the same. (I said Java, Data Structures, CN, DBMS)

How many traversals are there in tree? Explain all with algorithms.
Why is BST better that Binary tree?
He gave me equation and asked me to write prefix and postfix notation.
He gave me 2 code snippets in cpp and 1 in java.

12 Students were selected after this round.

Round 4: (Professional Fitness Round, 30-35 mins)
Introduce your self
Detect loop in a linked list?
What Sorting algorithm you know? What is quick sort and its time complexity?
What if pivot is at first index in quick sort?(He tricked me a lot here, but be on your point if you are sure)

If you are given number of nodes in BST how will you find the height?
What is Height in BST proportional to?
