SAP Ariba Interview Experience for SDE-I | Off-Campus

Got referral through contact from LinkedIn. 3 Rounds.

Round 1 – Technical Round -1hr

• The output of the below 2 codes.

Java

class A {
    public int getId(String a) { return 0; }
    public int getId(List<Integer> a) { return 1; }
}
class B {
    public static void main(String[] args)
    {
        A instance = new A();
        System.out.println(instance.getId(null));
    }
}

Java

class A {
    public int getId(String a) { return 0; }
    public int getId(Object a) { return 1; }
}
class B {
    public static void main(String[] args)
    {
        A instance = new A();
        System.out.println(instance.getId(null));
    }
}

I was not very good at Java, have answered these 2 in reverse. I said I’m good at DS&Algos so he started asking about them.

• https://www.geeksforgeeks.org/bottom-view-binary-tree/ (Approach was sufficient)
• https://www.geeksforgeeks.org/search-an-element-in-a-sorted-and-pivoted-array/ (Asked to write code)
• Was able to answer both the programming questions. He looked very satisfied with his approach and explanation.
• Asked if I knew Multi-Threading. I said no.
• Few questions on OOPS. Answered.

Selected for next round,

Round 2: Technical Round

Time: 1hr

1. https://www.geeksforgeeks.org/linked-list-vs-array/
2. https://www.geeksforgeeks.org/queue-using-stacks/ (Had to code)
3. https://www.geeksforgeeks.org/recursively-reversing-a-linked-list-a-simple-implementation/ (Had to code)
4. https://www.geeksforgeeks.org/print-left-view-binary-tree/ (Approach was enough)
5. Explain Docker to a Layman. Containerization vs Virtualization.

The interview went well IMO, but the panelist made sure I remained uncertain throughout. Was testing the confidence.

Got a call for the next round

Round 3: Managerial Round

Time: 1hr

1. Many behavioral questions. Asked about previous projects, why I am not so strong in Java. How do I plan to get strong in it?
2. Design Tic-Tac-Toe algorithm

I did not get a callback, so I dialed after a few days. The manager said that it is most likely that I would not make it through. I asked for feedback, but he said he couldn’t share anything at that point. Considering the way it went, I think my notice period(3 months) could have been a blocker.

Anyways, good experience. All interviewers were friendly and helpful.
