Hi, 1) you can not change OG especially from Gov, becuase they are bleeding for staff.2) if your base is london, the only sad thing that will mean is thats wehre your empty apartment will be. lots of my mates from here in london have been in leeds for years. 3) are you in strategy? this would change circustances greatly4) the executive interview will be a breaze, a chat / case study with a senior manager / partner. be positive, smile, and use words like 'value' 'synergy' and 'high perfomace' ever 5 seconds. also, be sure to listen VERY carefully when your interviewer identifies himself to better change your answers ( ie if he is CHT cv products vs Gov)and also, please be realistic in that you WILL go to the NHS. it is thier biggest contract and 45% of the workforce is deployed there. hope this helps.
