You will have to be more specific as to which are you are looking to apply to. Also, an FYI, Deloitte Consulting is now called "Deloitte MCS Ltd".As with every question on this forum, the answer to your questions is 'it depends'.You could be working on Slough trading estate where you need to be on site 5 days a week.You could be working in Soho on a media client where you will rock up in jeans and leave at reasonable hours every day.You could be working 18 hour days, or 8 hour days.I don't think there is one answer to your questions, a lot of it depends on who you are, what you want, what project you are on, how much the people around you like you, how good you are at networking etc etc.Personally with all consultants, I'm sure they have had times when they have worked an easy 6/7 hour day and times when they have worked 20+ hour days. It depends.
