I have also hone through the same situation in July 2018. They confirmed me in telephonic round, call for in person interview where I have answered almost all the questions. Still they didn't give any response for 20 days saying u r on hold and after that rejected me. U travelled from Bangalore to Kerala for that particular interview. I advice don't go there ask them to have skype interview. Otherwise all ur money will be wasted. They are just encouraging Kerala tourism.
