The first call was an HR round with the CTO which lasted around 15 minutes. This was followed by another round with a couple of their developers who went into detail regarding my resume, work history as well as past projects. The conversation was simple enough with basic questions on my skills.
Then I was invited to complete a technical challenge which was to develop a fully featured, production ready website deployed on a web server. Doable , but 3 days to design, develop, test and deploy the site was cutting it too close.
Havent heard from them since....
