Samsung came to our campus in the 7th semester for providing the Full-time roles of SDE-I. It allowed all the students to have a CGPA of more than 7 and no active backlogs currently. I was able to sit because my current CGPA was something around 8.
Preparation: I started my preparation 1 year before the placement season. For clearing Technical Interviews, DSA must be well-learned. For understanding the workings of C++ and its functionalities, I follow the lectures from Striver’s Youtube channel. Learned about Stacks, Sliding Window, and Dynamic Programming from Aditya Verma’s youtube channel. Hard topics like Binary Search, Binary Search Tree, Binary Tree, Graphs, and Heaps are learned from the TakeUForward youtube channel. Then I graded the whole 455 questions’ Striver AtoZ DSA sheet with hard work.
After that, I felt motivated for the Technical Rounds. The description of rounds is as follows:
-
Round 1: (Online Assessment):
- In the first round, there was only 1 DSA question, which was one of Dynamic Programming’s hard questions. The questions were Burst Balloon Burst Balloons | Practice | GeeksforGeeks. The number of submissions is limited to at most 10 times, while one can compile the code as many times as want. There were in total 50 test cases and only those will be selected for the next round, who will pass all of these 50 test cases. If any of the 1 test cases got failed, then it will be a disqualification for that candidate. Hopefully, I wrote the correct code and passed all test cases.
-
Round 2: (Technical Interview):
- This was an on-site technical interview. The interviewer was a 2 Years of experienced SDE. First, he introduces himself and then told me to introduce myself. I introduce myself after that educational background and then about family. Then he gave me a DSA question and asked me to provide an optimized approach to the question. the question was maximum length sub-array of sum 0 Largest subarray with 0 sum | Practice | GeeksforGeeks. Hopefully, I go through the same question before and be done with the same. The interviewer looked satisfied with the approach. It was an easy round.
-
Round 3: (Technical Interview):
- Another Technical round took place, this time interviewer was an SDE of 5 YOE. He asked me about the experience of previous round. I told him about the question asked and the approach provided in 2nd round. Then he asked me some of the basic CS fundamental questions. Then he gave me a DSA question Bottom view of Binary Tree Bottom View of Binary Tree | Practice | GeeksforGeeks. I provided the optimized code with O(N) space and O(N) time complexity. The interviewer looked satisfied. I was in believing that I will clear this round surely.
-
Round 4: (HR Round):
- It was the last round, This time he was an Interviewer having 8 YOE. He asked me about the experience of the previous two technical rounds. After that, he moved on to my project. I mentioned two projects in my resume one was an Android Chat Application and the other was based on a concept of Machine Learning. He asked me about the working process of both projects one by one. Mainly, he was interested to know If I know the basics of the project or not. I answered all the questions asked by him and he looked quite satisfied with all of my answers. After that, he told me to leave in a gentle manner.
Verdict: Selected
