MacDFor over three years now, I’ve billed over 210 days per year at and average rate above 750, so it can be done. My engagements are on complex projects that run 6-12 months. Mainly financial services (both retail and investment banking) and change management – I work either as an SME in a few areas of financial risk management, or as a Programme Manager. I’m early forties, large consultancy background, made it to just below partner before deciding that life was not for me.My current engagement is for a large bank, managing a team of 25 people who assess the impact of a new TOM on a segment of key customers and prepare the bank and its customers for that change. I run the team, manage director level stakeholders, create the business case/budget, manage risks and dependencies across a complex political company, etc – basically I’m a “client manager” in consultancy role terms.Each time I’ve finished an engagement, I’ve generally had at least one new option that starts the following Monday. Occasionally I drop my rate for a short period to keep in with a major client and this normally brings hom emore, better paid work as a follow on.My work comes through a small number of high quality interim management agencies and increasingly from recommendations within clients. Many of the “agency” jobs I actually source myself, but need to work through an agency for invoicing/insurance reasons.I’d say junior/mid level contractors can struggle in terms of career progression – generally they are hired to do what they have proven they can already do. Ironically more senior people still enjoy upward career progression, as their skills are in shorter supply and are hired not for “skills” or “knowledge” but for traits such as judgement, ability to deal with complex politics, ability to hire good teams, structure governance models, etc. More than anything its about giving very senior bankers the confidence to “leave it to X get the job done” while they get on with their day job.In the last three years I've worked zero weekends, never been in the office before 7am, almost always get the 6pm train home and have spent no more than 10 nights away from home. I would earn more as a partner (if I made it), but lifestyle is more important to me.Bit of a brain dump, but there you go...
