This is surely a hot button topic. I can say that my first BoR as a scout I was told to think of them as practice for a job interview. I also recall being sent out and starting over again. My last BoR with the troop was for Eagle ahead of district (Eagles faced troop and district Boards in my area and time). I was complimented in how much I had improved and assured that I would do well in job interviews.
The thing is that I have always done well on job interviews once even staying for an interview in a job I was not qualified for. One member said he wanted to find some way to qualify me as he was impressed and sure I could learn the job. Another time I was told I was granted the interview only because he saw that I am an Eagle.
I will also say that at this stage in my life I look for an exit for any interview which seems adversarial. When such has resulted in a job offer, the job wasn’t a good place to work for me. (I realize others may have a different view.) I can also say that my experiences in scouts has affected me when I was on the other side helping conduct an interview.
