The legendary "I de find developers" article and Hotels.ng's implementation of a remote internship are great examples of good theory and practice which have helped in solving a wicked problem of technical talent in Africa at scale.
Ultimately, like any other industries African technology businesses in each vertical must eventually come together to create standards and shape the future of their industry, any forward thinking African technology company should think seriously about actively contributing to open source projects.
The first example that comes to mind is MasterCard and Visa working together under the umbrella of EMV but another good one is how Google, Microsoft, Yahoo and others came together in an open community process working on schema.org to form vocabularies for structured data on the internet.
If DLVR Logistics is to hit our goal of contributing up to 20% of our development efforts as open source projects to the community, we need to be creative about how to do this - I'd like to see our open source philosopy and hiring process come together in a sustainable way.
Interested candidates would get to work on some of the big problems our industry faces by shipping something on our open source roadmap. This way we see if there's a real long term fit for the industries we're involved in, and applicants can apply their skills hand-on to solve real problems instead of another ultimately meaningless coding exercise.
