Got the call from its recruiter & she was thinking herself very smart. Then had the technical discussion with some Architect there about the general topics. Second round was taken by some other TL there. In short, maximum time these interviews are fake & waste of time for the candidates. These people are just taking the interviews if they can trap someone for a very low salary & then bill highly for the same person from their client to mint their own money. So never ever go for such company, as they will be speaking very sweetly till you don't join there & then they show their true character i.e. they have no character.

2 rounds of interview and 2nd round was the client round they are just expecting what they want even wtever the answer you give they won't accept so it's better not give interview
