OkCredit Senior Android Developer interview questions

I applied through job staffing agency And had 6 rounds After having all rounds HR said feedback is positive and will process further. And then after 2 days HR messaged that I have not been selected I mean you guys are taking rounds like Google for a Copied Idea and not a great or fancy app. You guys wasted my time and patience and this is really very unprofessional , It seems like in lockdown you do not have any work to do so you are wasting candidates time to show your work.
