I applied in-person. The process took 1 week. I interviewed at Code Ninja (Kendall Park, NJ) in Jan 2019
Interview
Came in, asked me a few general questions. No coding experience required. That was it, one 1:1 interview. They are looking for someone who can lead, help, and teach kids. From what I've heard though the pay isn't the greatest. It's a part-time job.
