"Dear Steve, Hope you are keeping well. I owe you an apology, I had promised to let you know how my job searching transpired; I can't believe a year has gone by already.

I have spent almost a year now with XXXXXXXX Consulting (top 5) which has proven to be an invaluable step, however, I have just accepted a role with XXXXXX (big oilco) - I guess what I was ultimately looking for. It is a really great opportunity which gets me out of indirect spend categories and back into operational areas.

I also wanted to thank you for crafting a great CV, it always gets me the interview and I still have head hunting agencies call me up from time to time; in fact just had to turn a great role down this morning."
