NTT DATA Project Manager interview questions

Applied online, contacted by HR for initial chat and salary expectations. Agreed to be put forward for £X amount. First round was a general Q&A with a few competency based questions. Passed and put through to 2nd round with 2 senior managers. General Q&A, case study / scenario based presentation, competency based Q’s. Pleasant experience both rounds , nice people, positive feedback received during both rounds. Contacted a few days later by HR offering the role - however dropped the salary on offer by almost £20K. Waste of time for all involved in the end.
