Interview Experience 17 (Intern)

##1st round(Online coding Round) (cgpa bove 8.5 for CSE/IT and above 9 for ECE)

There were 2 coding questions.

1. A simple question on greedy.
2. A DP question

I was able to solve first question only, in 12 mins(time is important)

##2nd round(Technical and HR)

###Technical:- (Around 35-40 mins)

1. They gave a practical scenario and asked me to come up with the best sorting algo for that.
2. Add two numbers represented as a singly linked list.
3. To print all root to leaf paths of a binary tree.
4. Balanced parenthesis (easiest one :D ).
5. Converting a tree to its mirror tree.
6. What is polymorphism. What is run time and compile time polymorphism.
7. They showed me some c++ code( of inheritance, copy constructor etc) and asked me what will be the output.

###HR Round(Around 15 mins)

It was interesting and simple question were asked. Introduce yourself. What are your future plans? A little about my project. My interests.

##3rd Round(Technical -- around 30 mins)

This time they mainly focused on oops concepts. (I suggest you to learn oops in depth.They asked WHY and HOW a lot :D )

One DS question (reverse a sentence as well as words) I did it using two stacks.

Then they asked what is 0-1 knapsack problem :D (easy one)

After that they asked a lot about my project(I did a project in NodeJs and Raspberry-Pi) like what is blocking code? why nodejs? About Raspberry-Pi? some more questions on nodejs and javascript.
