Preamble I have started cleaning up and updating my Github account https://github.com/dpweberza as more and more companies these days are likely to view it. Because I don’t have many open-source projects, I have uploaded a rather meaty coding challenge that I completed back in 2015. The Coding Challenge In 2015 I interviewed at a global mobile payments company for the position of Android Developer. At the time I had no commericial Android development experience but nevertheless was invited to complete a coding challenge after I had passed a screening call.
