Apisero Test Automation Engineer interview questions

I have worst interview experience with Apisero, it took 3 times rescheduling to take first round of interview. So unprofessional employees and interview panel. took total 3 round on interviews to evaluate/reject a candidate for which i have to be available late night( post 9PM )on the name of Client rounds. Probably there is some issue in their panels who needs 3 interviews to evaluate the candidates. I don’t understand, how they decided my rejection based on only 3 questions in last So called COO round which I answered all of them correctly. Btw thanks for this disgusting interview experience.
