Ques. Introduce yourself to the readers
I am a friend who loves learning new things, maths and friendship. I also likes to teach because teaching is the best method to learn.

Ques. Tell us about the written/online test. (Aptitude, Coding, Test Platform, etc)
Round 1 (45 Minutes): 30 MCQs, questions on databases, data structures and operating system. 42 students cleared round one.
Round 2 (90 Minutes): Four coding questions on cocubes.com
Question 1: Remove the duplicate character from a string.(5 Marks)
Question 2: Rotate linked list by k nodes.(5 Marks)
Question 3: Rearrange a given linked list in-place.(10 Marks) Example: Input 1->2->3->4->5 Output 1->5->2->4->3
Question 4: Minimum cost path in a matrix(variation of this question). (10 Marks) I did two 10 marks questions. Students who had selected after this round done either all 4 questions or 2(10 marks) &1(5 marks) or 2(10 marks) question. 18 students cleared this round.
Suggestions: Do some practice on cocubes.com, if possible. On cocubes, if STL does not work and if you are coding in c++ then always remember to write using namespace std at top.
