The first round was primarily focused on DSA and core computer science fundamentals. Questions Asked

1. Binary Tree The interviewer asked: What is a tree? Draw a tree. Write the traversals of the tree. Write code for: Inorder traversal Preorder traversal Postorder traversal I was expected to explain the traversal logic and write the corresponding code.
2. Binary Search Tree The interviewer then asked: What is a BST? What properties does a BST satisfy? Write code to insert a node into a BST. Write code to delete a node from a BST. For deletion, the different cases such as leaf node, one child and two children were relevant.
3. Array / Binary Search The interviewer gave an array containing only -1 and 1. The array had the property that all -1s occur before all 1s. For example: [-1, -1, -1, -1, 1, 1, 1] The task was to find the minimum index at which 1 occurs. The expected idea was to recognize that the array is sorted with respect to the two values and use binary search to find the first occurrence of 1. How It Went The technical round was focused more on fundamentals and problem-solving rather than extremely advanced DSA. The interviewer asked me to explain concepts, draw the data structure and then write code, so being comfortable with explaining the approach while coding was important.

The second round was primarily a behavioral interview. The questions were mostly industry-standard behavioral questions, focusing on: Introduction / Tell me about yourself Why Samsung? Why do you want to join Samsung R&D? Strengths and weaknesses Handling pressure Teamwork Handling disagreements Learning new technologies Failure and mistakes Handling feedback Motivation Career goals Situational / hypothetical questions Questions related to projects and experience The interviewer was mainly trying to understand my communication, attitude, adaptability, teamwork and willingness to learn. How It Went The round was conversational rather than heavily technical. I focused on giving honest answers and supporting my answers with examples from my projects and academic experience. At the end of the process, the HR team congratulated the selected candidates and took a group photograph with the selected candidates in front of the campus icon. I subsequently received the official selection mail.
