I probably sent several hundred cv's, letters and applications in 2006/07 when I was applying for jobs. Believe it or not, but I received only 1 formal written reply. A very kind chief pilot, of a very small airline(now defunct) based in Aberdeen, kindly took the time to write a personal letter to me and explain the recruitment process and company requirements. It wasnt a bog standard pro forma letter either, it commented on several things i'd said in my covering letter to him. I still have the letter, I keep it filed away. Well done Captain P M!!
