Samsung Interview Experience for FTE (On-Campus)

Samsung R & D Institute Bangalore visited our campus to hire FTE for 2022 and interns for 2023 for the role of Developer.

Eligibility: 7+ CGPA

Total 4 rounds were there- 1 online assessment, 2 technical interviews, and 1 HR round.

Round-1: Online Assessment: It was conducted on the cubes platform. We were given 2 coding questions to solve in 90 minutes.

• Find the next greater number with the same set of digits
• Check if the two Trees are Mirror

I solved both the problems within 25 min and checked for different test cases manually for more than 15 mins. There were only two test cases were visible and the rest are hidden. Even After submission, they didn’t show us whether all test cases pass not. So, before submission doesn’t forget to check for corner cases manually. One needs to pass all test cases as low as time possible. 

Round-2: Technical Interview-1 (20 min): We had to schedule the same google to meet link for 90 days and shared the link with Samsung.

• Introduce yourself.
• The data structures you know.
• Tell about PreOrder, InOrder, PostOrder traversal of a tree.
• How will you implement a queue using an array (Circular Queue Concept).
• Tell about BFS, DFS.
• Basic OOPs.

They didn’t ask me any coding questions in this round but other candidates were drilled by the coding questions. 

Round-3: Technical Interview-2 (40-45 min):  The interviewer was friendly and helped to think the right way.

• Introduction.
• I had an ML project. He was interested in that and asked me to explain the project in detail.
• How a CPP program runs.
• How to accommodate main memory to run a movie seamlessly.
• Demand Paging.
• How to choose a process from the ready queue.
• Keep track of the three largest numbers from a stream of integers.
• Which data structure would you use in the database to store 100k+ data.
• How do you store student data so that the time complexity of finding a student is less. (I told you about the HashTable strategy, but computation time will increase for large data. Then I told about Trie using unique Roll No. He was satisfied with that. I explained how to implement trie and how trie will work in this case.)
• Do you know about the graphs? BFS? DFS? How do they work?
• Explain Dijkstra Algorithm. 
• What is Priority Queue.
• How to implement Min heap using a priority queue.
• Virtual Function.
• Real life example of data structures you know.

He asked 1-2 questions from OS, I never heard of those terms, so I don’t remember them,

Round-4: HR Round (15 min): The next day HR round was scheduled.

• Introduction.
• What are the projects I’ve worked on till now.
• Why Samsung.
• How was the experience of the previous round of interviews.
• What are the technologies I am interested in.
• What are the improvements you want to make on this.
• Whether you use any Samsung products or not. 
• Do you want to relocate?

In the end, I’ve asked some questions about work culture and ongoing tech stacks in Samsung. 

Verdict: Selected

Note:

• Good with Basic CS subjects, especially OS, OOPs, DBMS.
• Go through all the previous experiences till you will get new questions, it will give you confidence.
• Think out Loud. Talk with your interviewer, he will help you.
• Prepare DSA logic well. I was a bit unlucky but they asked for coding for many students.

Good Luck !!
