That's what HR fight against all the time - people wanting to recruit in their own image Yeah, that's good, it's good that there are systems to counteract lazy, ineffectual recruitment strategies. As you say, Xenia, when companies recruit more widely they do tend to get better people.
Xenia's points about matching employees to candidates are half right. Obviously if you're recruiting for a role where entertaining clients is important then you do want someone who has, at the very least, great communication skills and the ability to adapt them to different audiences. The funny thing is that social soft skills are an area which parents tend to be least 'pushy' about - we tend to presume that our kids will just pick this sort of thing up - and some people have them and some people don't. But again, it's obstinate to pretend that class doesn't come into this - it obviously does. The extent to which that's acceptable (if you care about it at all) depends on what Xenia means by 'someone who cannot talk well". If you mean 'someone who knows how to conduct themselves in professional manner to suit a variety of situations', then that's a commercial necessity, yes - if you mean someone who has the wrong accent....well that's something I have very limited sympathy for. Even then, it's difficult to gain some of those professional social skills if you're not habituated to that professional environment and its social norms - so, again, class comes into the recruitment process here. And again, presumptions about class and appropriate leisure interests are evident in Xenia's statement that "Giving children enough so that they will have things in common with those with whom they might work is always a good idea."
Personally, I don't share hobbies with many people I work with (to my knowledge) and it doesn't matter a jot. But if you are all agreed that cultural capital plays a strong role in recruitment for middle class jobs - then how can you hold that position and also claim that class is irrelevant here?
As for relying on extra curricular activities and holiday pursuits as a tier of the recruitment process. If the candidate can make a strong case as to why the skills they demonstrated in that hobby/pursuit are relevant in the role they seek - fair enough - but making that case is a skill in itself. A candidate who can clearly and cogently explain why their experience of singing in a choir has developed skills the role requires is a lot more impressive to me than a candidate who has an Olympic gold and expects that achievement to speak for itself. As far as I'm concerned, if you can't explain why it's relevant to me in this role, then you might as well not have done it. Similarly, if this candidate who biked across Vietnam could offer many examples of skills and attributes he developed or demonstrated on this journey, then yes, I'd treat that as relevant experience. But if someone was just impressed by someone going on a long haul holiday that barely any other young people can afford, in terms of time or finances, then I guess that person wouldn't be a very good interviewer.
