I was interviewed at Ciena Gurgaon. I have 3+ years of experience.
Round 1(1 hr):
- Implement your own smart pointer class
- Copy Constructor
- Assignment operator
- Given a linked list modify it such that all the odd elements appear first followed by all even elements reversed.
Example -> Input: 1->2->3->4->5->6->7->8 Output: 1->3->5->7->8->6->4->2
It was similar to this: https://www.geeksforgeeks.org/segregate-even-and-odd-elements-in-a-linked-list/
Round 2(1 hr):
- Given different service providers, their prefixes, and call rates. For a given number, find the service provider whose prefix matches with the number such that the call rate is minimum.
Service Provider 1 972 .1 Service Provider 2 9725 .02 Service Provider 3 97250 .04 Service Provider 4 97254 .06 Service Provider 5 972 .02 Service Provider 6 9721 .02 Number = “9725434567”
In this question, the interviewer asked what Data Structure will be used to store this information of the service provider and later asked to find out the minimum call rate for a given number.
- Implement your own vector class.
Hope it helps!! Good luck
