What the HR person would know is how the person appears socially and how he manages to present himself.
The company should make sure the HR person isn't the only one deciding if somebody gets hired or not, because the HR person simply does not possess the tools needed to get the best man for the job by himself.
True story: I got an ad for a consulting position for "Postgre"
The description had as a listed skill:
"PostgreSQL USE GOOGLE TO VERIFY SPELLING"
That's a bad sign there.

It's easy to bash HR people just as "regular" employees often bash IT ("They won't provide that simple feature that I've been asking for ever since, just because they hate me."). But calling the role "broken" does not magically make it disappear. Someone needs to handle the employer/employee relationship and all attached nuisances - any organisation with employees that does not handle this role is more broken than any HR department I've ever seen.
I'd really hope that we'd be over this and appreciate that other people in our organisation provide value and experience that we maybe can't see at fist glance. Instead we close our eyes and call their role "broken".
The scope can be as narrow as "do background checks on hires, do the math on their desired pay and tell me how much each one would cost and if there's any red flags" or as broad as "do a first phone call and check out if you think that person is a good fit culturally." Handle all associated paperwork, set up interview dates, handle travel and accommodation arrangements for the prospective hire, ... Handle all paperwork associated with employees, sick leave, keep track of holidays, ... Follow changes in applicable law. Organise team building events. I know of an HR department that organises monthly lunches where people of the company get randomly assigned to groups so that they get to know other people working in the same company, not only their team peers. There's a lot of things you can do as HR person. Not everybody needs everything and not every HR person may have the required qualifications for each task, so you probably just have to figure out what exact set of responsibilities right for your place.
Out of curiosity, could you imagine an organization functioning where HR work was done by administrative assistants to team managers?
No. Mission creep happens on broad and narrow roles the same. The better defined the role, the better. Constant reevaluation and adaption to changed realities is a must.
> Out of curiosity, could you imagine an organization functioning where HR work was done by administrative assistants to team managers?
Up to a certain degree yes, but there's the question how and where to allocate common functions if you have any. Depends on your organisation. That doesn't make the "HR department" disappear though, it just changes its name to "administrative assistants". It certainly makes things harder when people try to reach the HR department because that's what they're used to.
All in all: If that fits your organisation, sure. Just make sure that the role is defined and someone is responsible and actually takes up the work.
edit: see also https://news.ycombinator.com/item?id=6289282 for a point where a more centralised HR made a positive impact. An assistant to the team manager might easily have missed the broad picture because of a more narrow view, focused on the teams turnover rate.
We had an initial round of meetings and then the issue slipped with meetings getting pushed out further and further from the other side. So yes, I think that in this position the other person was in charge. In any case, even if I'd be responsible to push the agenda, a good HR department should not let an open (and known) issue slip. Quite, to the contrary, good HR should recognise situations like this before the employee ever feels the need to push for a contract renegotiation.
If you get a moment, read "Corporate Confidential" by Cynthia Shapiro. Only 200 or so pages, and it's a quick read. But very enlightening.
That's only true if the people defining the mission of various departments -- i.e., executive management -- is not competent at their job.
Reforming or eliminating HR will not fix that problem.
