SIXT Interview Experience for SDE-1 (Off-Campus)

 I have recently given an interview for the SDE-1 position in Sixt R&D Bengaluru, India. 

There were 5 rounds and all happened online:

• Online assessment
• 2 Technical Interview Rounds
• 1 Managerial Round
• 1 HR round.

Round 1(Online Assessment – Test duration: 1hr 30min): The test was conducted on the HackerEarth platform.

It had 2 sections:

1. Some technical MCQ questions (around 15 questions)
2. 2 coding questions

The technical aptitude part covered questions from operating systems, DBMS, data structures.

Round 2: (Technical Interview Round 1 – Duration: Around 50 mins): The round started with my introduction followed by 2 DSA questions. I was given a link where the screen was shared between the interviewer as well as the student, where we can write the code.

1. Find the common nodes in two singly linked lists: https://www.geeksforgeeks.org/find-the-common-nodes-in-two-singly-linked-list/
2. Print all the boundary nodes of a binary tree

   Example: For binary tree shown in image the output is :{ 20 ,8 ,4, 22, 25,10 ,14 }

   

   I was able to write PseudoCode and dry run both the questions, and the interviewer was satisfied by my approach and the code.

Then the interviewer asked questions from DBMS, OS

• SQL query on self-join
• Singleton design pattern

This round ended after I asked some questions to the interviewer.

Round 3: (Technical Interview Round 2 – Duration: Around 50 mins): The interviewer asked 2 DSA questions and a link was given for writing the code.

1. Detect loop in given linked list and discussed time & space complexity: https://www.geeksforgeeks.org/detect-loop-in-a-linked-list/
2. Connect siblings in a binary tree(connect only leaf nodes). Given a node with either 0 or 2 children. Connect the left leaf child with its right leaf child at the same level and return the updated tree.

   Example:

      Given:                  Output:
         A                       A
       /   \                   /    \
     B       C                B      C  
    /  \    /  \            /  \    /  \
   D    E  F    G          D -->E  F -->G

Questions on OS and DBMS topics

He asked: Any questions you would like to ask? and I asked some questions

Round 4(Managerial Round – Duration: 45 mins): The interviewer initially asked me to introduce myself

• Then asked about my last semester’s subjects and projects of last semester in college.
• Asked about my favorite subjects and I said OS, DBMS, computer network. Then he started asking questions from them including topics memory management, Semaphores, paging and threads, multiprocessing and multiprogramming, ACID properties, Self join(explanation with example)
• Then we started discussing one of my projects mentioned in the resume. The discussion went for around 15-20 min.

 This round was more like how you express yourself and also how well you can explain your projects and ended up me asking questions to him.

Round 5: (HR Round – Duration: 10-15 mins):

• In this round, he asked about my background and hobbies.
• Why I wanted to join the company.

Basically, he wanted to know my interest to join the company.  

So, this was my interview experience. Hope it helps.

Verdict: Selected

Note:  

• Every round was an elimination round
• let the interviewer know what your thought process is by making him dry run your approach with an example.
• Be calm and keep trying, interviewers are very helpful
