Atos Project Manager interview questions

Initial screening by Internal resourcing team representative who also checked my expected salary range. He later informed me that a face-face interview will take place in London and it had to be a face-face interview because a decision will be taken based on the same. I had to take a day off and travel almost half a day to reach London for interview. I was also told to prepare a presentation on a given scenario for the two interviewers. Interview was pretty good and Interviewers seemed knowledgeable and questions were of good standard. Couple of days I got a call from the resourcing guy who told me that they are happy to put forward and offer and not so happy because he knew that I am going to reject it as it was nothing like we had discussed. The base salary was lesser that my current base salary and they wanted me to work from Reading for that. The guy who called me didn't have any decision making authority and was following orders from his supervisor.. I declined the offer !!!!
