Samsung R&D Bangalore Interview Experience (On-Campus 2019)

Round 1:

It was a 3 hour long online contest and there was only one problem.

Question :- Given a graph tell if graph is bi-parted if yes then print any one color all node. There where 10 test cases and no STL were allowed to use.

Those who cleared all test case were allowed to sit in next round. Total 90 student applied and 3 student got selected for next round.

Round 2:

Technical Interview-1:

1.Introduce yourself and about your projects.

2.Explain  TCP/IP and one protocol from each layer.

3.Given 3 router A, B and C connected in linear fashion(A-B-C). A router want to send packet to C router. You know IP address and MAC address then tell which data  will change during packet transformation.

4. Different between packet switching and circuit switching.

5. Different between AVL and Red-Black tree.
