Linkedin Internship Interview Experience
First round was online coding round. It was hosted on hackerrank platform. 4 questions were there.
6 people were selected for next round.
Second round was telephonic interview. We have to write our code on a real-time collaborative code editor on skype.
Firstly interviewer asks me about myself. Then 2 coding questions were asked.
- Find total number of visible nodes in a binary tree. A node is visible, if it has highest value in the path from root to node. It was done in O(n).
- Find leftmost unique element in the array. eg. 2 5 2 3 5 6 8 . Answer is 3 for given example. I have done with the help of the hashmap in O(n) time complexity.
Coding style was given more importance than solution.
Finally 4 persons were selected. I was one of 2 who was not selected.
