Interview Preparation Tips
Experience: 1. Given an array and a number, check whether there are any 3 elements in the array which add up to the given number.
For example:
Given an array {1,2,3,4,5} and the number 9, return true, as 2,3,4 add up to 9.
Given an array {1,2,3,4,5} and the number 3, return false, as there are no 3 elements which add up to 3, in the array.
2. Given a number, find the nearest perfect square(modified binary search)
For example:
Given 50, return 49
Given 25, return 25
Round: Technical Interview
Experience: System: The user gives a book id to be downloaded and the location in which the book is to be stored. The system downloads the book (if it exists) in the location given by the user and returns a url through which the user can access the book.
I was asked to design automated test cases for the system. The interviewer kept adding more and more constraints to the system and we discussed about the pros and cons of my approach.
