SteelEye Frontend Developer interview questions

Interview process was quick and straightforward. It had 4 rounds in total: 1) Small coding task in React 2) Telephonic technical round mainly on React and Javascript 3) Chat with founders 4) HR Round

I was approached by someone at Steel Eye for a frontend rule. The entire journey has been smooth. The interview questions were really easy and simple and I almost answered all of them. But next mail I got rejected and when I asked for feedback there was no reply. I still have no idea why I got rejected all of a sudden.
