Perguntas de entrevista de vagas de Python Django Developer da empresa Keywordio

I applied online. Firstly one of their senior employee send me their django project..i cleared the first round of interview..then they schedule my 2nd technical round of interview..it was pretty easy.then they inform me to come to office for next technical round of interview. It was basic introductory round. Next he scheduled my technical round. It was actually good. the guy asked me basics of python,django and frontend technologies. I was really hopeful that I can clear this round. then after the last round they say they will contact me tomorrow..but Then no feedback after that. I mailed to ask my application status...they were not replying....Couldn't understand the reason. Plus I think there is no concept called HR in there. Senior engineers only mail you and contact you. What a waste of time!
