TV2Z interview questions

In first Techincal round interviewer asked me code on palindrome then after he increased complexity i had written code and asked some questions in React i didn't answered 2-3 questions . After Tr-1 i got mail again for Tr-2 in this round they asked totally Javascript advanced concepts questions i answered maximum and at last they gave me review that i dont had experience in other frameworks. Without asking questions on framework they simply rejected me.
