Just to let you know I was successful at my recent interview for Senior Executive Engineer with the Public Appointments Service and will be offered a position with xxx in the coming weeks.

May I take this opportunity to thank you for your assistance – it was invaluable.

The mock interview and feedback you gave me was very beneficial as it motivated me to prepare in the correct areas for the interview.

Other areas that I concentrated on and that really helped just before and at the interview stage were body language and the power pose as they helped me relax and gave me confidence.

Many thanks again and best of luck for the future.
