I applied online. Two weeks later, a recruiter sent me a link to a coding test, which consisted of three coding questions. Then, I was invited to the onsite interviews at the Microsoft offices in Cairo. Each interview was one-to-one.

Given an unsorted array of integers in O(n) time complexity, find the first unrepeated element in that array. For example: A = [1, 2, 3, 3, 2, 1, 4, 5, 6], the answer is 4.

Given an unsorted array of strings, count the number of repetitions of each string in that array.

Given an array of integers, find the element where the sum of elements on its left equals the sum of elements on its right.

Delete an element from a linked list.
