Dopple interview questions

I spoke with 3 separate people. The marketing director was very disorganized but overall a nice lady. I was then requested to do an un-paid project for them which took well over 3 hours. I moved on to the final round with Chao Wang and WOW-- was she the most rude CEO and overall person I have ever met. She interrupted several times to redirect a question and make it seem like I wasn't answering her questions by asking me more mid-sentence. We walked through my project but I could barely get a word in edgewise. By the end of the call I was still professional even though I was slighted the entire hour long conversation. I said it was wonderful speaking with her and she simply hung up. This was extremely rude, petty, and unprofessional. I sent a follow up email again as a courtesy for her time even though I didn't plan on accepting any offers if given one--and was completely ghosted. This company wont make it very long if you ask me and shame on Chao Wang for treating people like garbage.
