Applied through referral. First introductory call was from recruiter one evening (without prior email communication), asked basic introductory questions, JS experience and explained the role. First actual interview round over call was setup after few days. Phone interview was with probably with a junior developer from the Flock team. Questions were basic off-the-book type broad-based question, like explain let/const, inheritance, closure, Asked few JS questions, most of it went well. Never heard back from the recruiter about the last round's feedback or next steps.
