I'm looking for someone with experience with data structures, algorithms and online coding test environments such as hackerrank, codility or codewars. I'm going to take a 60 minute test which includes 3 short Python problems. Since performance and accuracy are very important, I'm gonna need someone to work out the solutions at the same time, so I can choose which one to submit. Since I need to submit extremely high quality code, considering all the possible corner cases, I need someone whose 100% confident in their ability to solve problems successfully (please check these examples: https://codility.com/programmers/lessons/12/). It's also crucial that we are able to communicate very easily on Skype during the test. It might be that we agree on working out the solution together, or separately, whatever is more efficient. We might want to try solving 1-2 problems before the test to make sure we can work together. I'll pay $25 if you send me 3 working solutions (you should aim to complete each of those in under 16 minutes). I'll pay you another $25 if we get at least 250/300 points (that is very realistic on the site, given that the code is somewhat efficient and it considers basic corner cases).
