I made React Native Demo. They got back to me right away: the next day. I spoke to the project manager and he asked me questions about my team and sprints. Then he asked me about my current role and how I use React Native. Then he asked me how I used React Native at my previous job in 2015. I told him I didn't use react native in 2015. He got upset and asked me how I used mobile native in my 2015 job, I told him I didn't and I have only used it the last year. He did not like that and said that they are hiring someone who has developed mobile apps for a long time.
