SunTec Business Solutions Java Full Stack Developer interview questions

Worst experience. Never trust them. They gave me a joining date with a hike of 60% and asked me to extend my current offer in hand (which was at EY). I did the same. 2 days later they kept ghosting, when I called the HR, she told me they are not okay with my package. I don't know what to do, I lost my existing offer by trusting these people. Please don't repeat the mistake I made. The overall process had 4 rounds which includes online assessment, technical round, hr and managerial round. I cleared every round only to get cheated.
