They approached me for interview and mentioned will be having two rounds and One will be a face-to-face. So should come down to client office. But they had almost 4 rounds of interview which they were mentioning as want to assure the candidate as client is not quick at response. Later after clearing all rounds they released the offer. Looked like a very disorganised offer and also after releasing offer they are not sure on joining date. I gave up the offer after multiple unwanted discussions and accepted the other assuring opportunity
