Domande di colloquio per Java Applications Support presso FIS

First I have cleared HackerEarth online test followed by 1 technical round and 2 managerial rounds and last onsite interview Round. 2 positions I was interviewed one was 4 Prophet product and other was WePay app and both profiles I liked. HR representative was very un-professional and despite of providing all experience details and skills details initially before confirmation, he keeps on calling and asking for same details repeatedly again and again till 2 weeks & still not confirmed to release offer after clearing all. FIS is having good reputation in market and would love to join but my interaction with HR spoiled everything. Despite of clearing all rounds because of his un-professional and non co-operative behaviour couldn't make releasing of offer.
