But I had a 45min phone consultation with them, sent them my old CV. After 2 days they improved it and that's when all the interviews started flooding in.
I doubt very much that a changed CV in itself caused interviews to suddenly "flood in", I suspect that if your old CV had been dormant on some recruiting portals then *any* update to it (assuming it wasn't dire) would trigger contacts from recruiters.
Likewise if you actively applied for roles after getting a new CV then...
Its not getting so many hits in google this time but when they were mentioned before then you could search for the below waffle and get a bunch of linked in profiles:
----------------------------------------------------------------------------------------------------------------------------
A highly experienced, commercially astute business leader with a wealth of high end professional expertise and technical knowledge, an individual with strong leadership and consensus building skills with expert man management abilities, and a proven track record of delivering results during every stage of the business life-cycle.
A self-starter and highly organised individual able to work well at all levels, with the ability to solve problems and make decisions enabling the efficient and timely completion of work. A professional business leader focussed on delivering first rate service on all projects from inception to completion through effective management and team collaboration
----------------------------------------------------------------------------------------------------------------------------
It doesn't really matter if they've changed the waffle, the point is just that generic waffle like that is such a waste of time. Everyone can proclaim to be a "self starter" etc.. and have an "ability to solve problems" etc.. who cares? It's totally meaningless.
It's a bit of a weird one I guess as I am sure there are services out there that will write you a cracking CV but just beware of the "churn houses" as described in my post. As I said at least half of the 300 cv's were near on identical in terms of layout, qualifications, length of sections etc. As a employer/decision maker I found it incredible that people seemingly couldn't be bothered to spend the time required to write a CV. Personally I have several CV's tuned for different roles, I have a managers cv, a proper techie CV and a cut down version that sort of includes both aspects. Depending on the role depends on how a gear the CV. To be fair though I have never had to use it as I have never had a proper interview, I have always been approached when not looking for work by people ive previously worked with. It probably helps that I worked for a small bespoke company that employed around 100 FD's who were put into FTSE and AIM listed companies on an interim basis.
