Round 1(Online Test): It was an online MCQ test.
- The test comprised of questions from DSA, DBMS, OS, logical reasoning, Flow chart analysis, etc.
- There was no negative marking but the time limits were very strict and also there was no going back and forth in between questions.
- So keep an eye on the timer and solve as many as you can but try to attempt all the questions.
- After this round around 40 students were shortlisted for the interviews.
Round 2(Technical Round – 1): The interviewer was very friendly. He asked me whether I was feeling good.
- He asked me to introduce myself.
- Then he asked me to explain the project that I mentioned on my resume.
- He asked me some questions that were related to my project.
- When I was asked about my favorite subject, I told him DSA. So he told me to solve a question. The question was to find the factorial tree of a given number(https://www.geeksforgeeks.org/factor-tree-of-a-given-number/amp/). I was able to solve that question and then there was some discussion on time complexities.
- Then he asked me if I had any questions. I asked 2 – 3 questions regarding the company culture, etc.
Round 3 (Technical Round – 2): The interviewer asked to solve a coding question.
- I was given a string and I need to partition the string in such a way that no character should be present in more than one partition(https://www.geeksforgeeks.org/maximized-partitions-of-a-string-such-that-each-character-of-the-string-appears-in-one-substring/amp/). At first I felt it was difficult to solve. After some brainstorming, I told my intuition and the interviewer looked convinced and then I was asked to code the same.
- After this, she asked me some questions about my project.
- Then she asked what is object-oriented programming.
- She then asked me to give a real-life example of polymorphism.
- Finally, this round ended with a question on DBMS(Is it always necessary to have a primary key in any relation? What happens if we don’t explicitly declare a primary key while creating the table schema).
Round 4(Technical Round – 3): The interviewer started with a maths puzzle. Find the four-digit number when multiplied by 9 gives its reverse and also no two digits are same(https://brainly.in/question/11208042).
- Next question was to find whether two strings are rotations of each other(https://www.geeksforgeeks.org/a-program-to-check-if-strings-are-rotations-of-each-other/amp/).
- Then I was asked to tell the approach to search a word in a 2d array of characters. I first told him dfs approach and then told him that trie data structure should be used. The interviewer seemed convinced.
- He asked me if I had any questions. I asked 2 – 3 questions and then it ended.
Verdict – Selected (A total of 10 students were selected out of 39).
Tips:
- Be prepared before your interview.
- Stay positive and confident.
- Try to interact with the interviewer, try to make the conversation flowing.
Finally, I would like to thank GeeksforGeeks for the invaluable support to all the students through these wonderful questions and previous experiences.
Thank you GeeksforGeeks.
