Uber Marketing interview questions

I applied online and was contacted by a recruiter another day. we scheduled a meeting in the following week and the questions asked by the recruiter were quite detailed to the job. it was a 45 mins talk and after that i was asked to hear back from her in 2 days. so after 2 days i was introduced to a manager in sfo . the interview with the manager was not like an interview, more like the manager was asking me thoughts and ideas about promoting uber. 1 week after the interview with the manager , i didn't hear anything from them until i sent an email to the recruiter asking about the feedback. the recruiter told me they decided to have another direction. i don't want to comment or argue that this start up is cheating the ideas from candidates or something because we all dont have the proof. but they way that they send the rejection letter only when i ask them is not cool at all. p.s. it's not a cool way to cheat the candidates in order to grow the start up.
