Euronet interview questions

All was good but it took them long time for each interview to be arranged. It was 6 rounds in total (!!!) I made it to the fourth round (after 1.5 months) to tell me I wasn't a good fit. Really? I get it, but why take 4 rounds of interview?

only one interview based on resume one coding question and the interview was held on another application .The interview was of 30 minutes and java related questions were asked .For some people they asked oops concepts moreover the basics must be strong to clear the interview
