Hello,I am due to move to London over summer from overseas. Could anyone kindly inform me of the type and nature of travel typically involved in working for one of the niche London based strategy firms (McKinsey, LEK, Bain, Bearing Point etc) - principally in their finance strat teams if possible? i.e. what (rough)_ percentage is it mainly on London based (the City) engagements, short trips to mainland Europe, or even long term (greater than 3 months) on client site elsewhere?I appreciate it can vary and there is no definitive answer - but advice is much appreciated.Thankyou in advance, best regards.
