I applied online. The process took 2 months. I interviewed at AtScale in Sep 2017
Interview
It was two sessions (phone screen and coding challenge). I talked with the hiring manager about my experience and how I got into working with JavaScript. The hiring manager talked about the company culture, teams, and the product at a technical level. Had a couple of questions about JavaScript during the initial phone screen. Coding challenge was through an online collaboration tool and using JavaScript and objects/inheritance.
