I hear you, I also would not join kids for a job interview, but have no problem calling someone to arrange it! Also, nobody ever came with a parent to the interview, even the one whose parent was my colleague. Maybe engineers are more mature than lawyers.
Still, we supervise more aspects of our kids than our parents ever did – and our parents do not object. I once asked my mother why she did not suggest me to do what I am now suggesting to a kid (and she agreed with the idea) – and she said “we simply did not think about it”.
