I applied online. The process took 2 weeks. I interviewed at Radical App in Jul 2017
Interview
Initial phone call 30 min resume review with technical mobile engineer. Haven't heard from them for a week. Got a positive response when I enquired about what's going on. Second round was technical with the same interviewer 1-2hr estimated. A web page screen sharing invite was sent to email while on call. Open to choose language of my choice. You can talk through your process to the interviewer while coding.
Didn't make it to next rounds.
