I recently came across a pile of letters. It would appear that I used to ask newspaper editors for feedback after an unsuccessful job interview with them. A surprising number gave it. Some of what the editors said was valid and in a number of cases there was something I could do to remedy the shortcoming they highlighted. In other cases the criticism was unjustified but the fault lay with me because I had failed to dispel whatever reservation the editor had. And in a couple of cases the editor was obviously barking mad and I could comfort myself with the realisation that I'd just had a close escape.
