Ahead of their first day, new Square employees are welcomed with "Launchpad," a tool for quick orientation, choosing hardware, and leaving a great first impression. A particularly important element is the choice of internal email name, something most employees care about. The field itself provides quick feedback if an invalid or already-taken name is chosen: the entered text turns red and shakes left and right. We also added suggested names based on the employee's name, to keep things easy.
Of course, the design needed to be mobile-friendly too, so it was built with a responsive layout.
