I received a call from Samsung through an employee referral. I was interviewed for a C++ position.

First Round: Written Exam Basic C++ questions. Please do prepare the basics. Everyone with less than 3 years of experience needs to appear for this written exam.

Second Round: Face-to-Face Interview Basic questions about C++, threading. Why do you want to leave your current company? Explain your current profile. One question I remember was to count the number of bits in an integer. All other questions were easy.

Third Round: Face-to-Face Interview Questions like "Define yourself?" Some basic questions related to programming (very easy). Sort an array that contains only 0s and 1s in the most efficient way. All other questions were easy.

After one week, I received an offer letter from Samsung. However, after some time, an HR representative called me again and asked me to visit the Samsung office to appear for an online test. I was a bit panicked, wondering why Samsung was asking me to appear for another test. But don't panic, guys; this is only for some internal process where every employee of Samsung must take this test. This will be some evaluation parameter for future hikes, but be sure it won't affect your offer letter.

Overall, the interview process was easy. The HR and interviewers were very friendly.

All questions were easy. However, my suggestion would be to please prepare data structures and algorithms.
