Have to disagree with the post above re C&HT travel requirement.
I recently left ACN after 4 years in C&HT (comms and hi tech) as a consultant. My experience wasn't unique (most of my C&HT colleagues had similar) and involved working 80% of the time in London or on the M25 / M4 corridor (commutable from London at a push). I spent short stints in Birmingham but most of my work was for clients in London, with spells in Croydon (joy of joys), 'exotic' Slough, Newbury and Reading. These glam locations are where most of the big telco clients are based or have major operations.
For me, Reading was about as far as it got for longer-term assignments, and some projects let consultants and analysts stay in hotels locally (down the discretion of the project management). I always chose to drive back to London daily if things weren't too hectic - though this did involve 6.30am starts and regular 11pm returns home.
Had the travel requirement been as heavy in ACN C&HT as it was in say, Resources or Products (I had friends in India, Middle East and Scotland for long periods of time), I probably wouldn't have stuck with the job for 4 years. I would reiterate the point above that if you are in a market unit other than Financial Services or C&HT and dislike travel, you are probably in the wrong place.
Good luck with your decision, I empathise.
