Python / Asynchronous DifficultyMedium Python
Given a list of numbers, this Python program finds the first unique element in the list. For example, given the input [1, 2, 3, 4, 5, 1, 2 , 3, 4], the output would be 5.
About this solution: The candidate's solution is correct and demonstrates a level of completeness. The candidate's approach is also correct, as it uses a dictionary to store the number of times each element appears in the list. This approach is optimal because it only iterates through the list once and then iterates through the dictionary once. Therefore, the time complexity is O(n) where n is the size of the list.

Python / Asynchronous DifficultyMedium Python
This Python program finds the sum of the even-numbered elements in a list. For example, given the input list [1, 2, 3, 4, 5], the program would output 6.
About this solution: The candidate's solution is complete and solves the problem. The candidate's approach is efficient, using the modulo operator to check if a number is even.

Python / Modules and Packages DifficultyMedium Python
This technical problem asks the reader to write a Python function that will sum all of the integers in a given list. An example input and output are provided.
About this solution: This solution correctly sums a list of integers. However, it is not very robust - for example, it would not work if the input was not a list of integers. Additionally, the function does not have any documentation to explain what it does or how to use it.

Python / Asynchronous DifficultyMedium Python
This technical problem involves implementing a function that takes in a list of numbers and an asynchronous function, and returns a list of the results of the function applied to each number in the list.
About this solution: The candidate's solution correctly implements the function and returns the expected output. The candidate uses the asyncio library to create asynchronous tasks and wait for them to complete. This is a good approach to solving the problem.
