EPAM Systems Automation Testing Engineer interview questions

One of the worst experience in interviewing in EPAM.They decide their requirements after taking candidate First round of atleast 1-1:30 hour. I have attended interview in epam recently after taking my first technical round for almost 2 hour.i got Cleared and for 2nd round i have new requirements which they got from their client. They asked me to learn APi automation framework design in 1-2 days with tetscafe ,graphql and few other tools which initially wasn't mentioned in their jd. And then in managerial(2nd round) rejected by saying I don't have experience in API automation. I wasn't expecting such unprofessional behaviour from such a good company. One suggestion please don't go for interview with epam as they don't worth your time and can reject you any time by giving any reason.
