It was about 10 years ago when I scored the largest custom software development and integration contract ever for my company.
The deal involved development and deployment of an SAP integrated BPMN solution, all over the world, for a multinational pharma company. 2 year development contract + maintenance extensions. Huge deal!
There were some very clear requirements regarding SAP integration expertise, involving multiple modules.
Up until that point we had done small integrations, involving only few of the required modules. The competition thought we were a joke, even one of the decision makers said that to my face, asking how dare I even want to make a propsal.
At that point we asked for a 15 minute technical presentation where we listed other, completely unrelated 3rd party integrations that we had delivered without prior experience, and then told them that we were engineers at heart and fast learners and that we enjoyed the challenges as long as they would also be willing to work with us in at least nudging us in the correct directions, and then we confidently explained what mattered would be the fundamentals of software integration, not the specific api endpoints and formats, and that we were the best they would get since we knew those fundamentals by heart.
2 years down the road, we received nothing but recognition and praises from all over the world, including that guy mocking us in the beginning.
So @a.com believe me when I say “the ability to learn blaze” is what translates into real life and it does so much much much more than “knowing angular/react/ember/backbone” ever can. Because a year from now, something new will have come along, sweeping all those stacks and that hiring manager will want to have been working with people who are willing and able to learn and adapt.
