Oracle Data Engineer interview questions

WASTE OF TIME ! Got call from HR, Asked to share my CV, After 6 good round of interview they felt that one of the skills needed for this role was missing. That's the one important thing the HR or the HM should have figured out even before you schedule any interview. Right ???? Time is important for everyone, please don't waste it. One complete productive weekday got wasted because of this act of ignorance.

it was a long process. first they asked me a few puzzles, then a few java codes. hr round was kind of peace. the interview exams were difficult and it is a great company to work with
