It is with deep regret that I must inform you of my need to leave (Company). After 8 Month employment with (Company), I find that my anticipated career goals are very different from the opportunities I am actually receiving in my current position. I value the time I have spent with (Company), and the friends I have made. This position has taught me invaluable lesson about the recruiting field, and for this, I am very grateful. I do feel, however, that a change in my careers plan is imminent in order for me to realize my full career potential. Thank you for your continued support and guidance.
I hope my departure does not place too much of an inconvenience on the (Department). I will be happy whatever I can to make this transition as easy as possible.
