That would be indeed implausible. But not every transaction happens between undeferentiated cogs.
A specific person organises the interview logistics from the company. Let’s call him Joe. When they agree with a candidate on an interview date Joe picks up the phone and calls the hotel to book a room. After that Joe calls George the trusted taxi driver they always work with. He lets him know who needs the ride and when. They exchange pleasantries. George also lets him know that the one on Monday cussed him out when he thought George was not driving fast enough. Joe laughs, and tells George that that’s crazy since he is always on time if not early. George feels good about that. He likes that Joe noticed that he is always punctual. They say good byes . Joe makes a mental note to not hire the cussing candidate.
What is implausible about this?
> How frequently are people so rude to the taxi driver that they are disqualified from consideration?
Have you met people? Happens all the time.
> Does the taxi driver get compensated?
Yes. He receives a steady supply of rides and the company pays him for that.
> Why is the taxi driver doing this?
He is a human being and those in general don’t like it when someone mistreats them. They let others know when it happens.
> Does anybody vet the taxi driver's personality testing ability?
Yes. It is called a personal connection. The driver behaves like a decent human being and only rarely say that someone was rude to them so the hiring manager believes them when it happens.
I think the reason you find this story implausible is because you are thinking on a different scale. A team of hiring managers managing 500 interviews per week for a megacorp can’t do this. They won’t have the mental bandwidth, they won’t use a specific driver, they won’t have the personal connection. Not every company is that size. Some company might only interview a few people a week.
It's also bizarre to me that the company would have a "trusted taxi driver". A trusted driver for executives or something might make sense, but a trusted driver who isn't employed by your organization that you specifically route candidates through? It just doesn't sound like the type of thing that happens much to me.
Finally, on the subject of people being randomly rude to taxi drivers, never having been a taxi driver I don't have real first hand information. I did ride a public city bus multiple times a day for years though and the number of people who I witnessed being rude to the driver, who were not visibly drunk or homeless, is zero. It just doesn't fit with my experience of humanity to think that, in a typical daytime taxi ride you're going to get much absurdly inappropriate behavior - i.e behavior that would rise to the level of disqualifying the candidate. Maybe if the taxi driver were a woman I'd believe it, but I bet the vast majority of people would just say where they wanted to go and little else.
Many years ago, in the days before Uber and Lyft, I lived in an apartment complex in Campbell, CA. There was a nice Ethiopian family a couple of units over from me. I would often smell the delicious food they were cooking, and they probably smelled the coffee I would roast in my Gene Cafe. I mostly roasted dry process Ethiopian coffees (and still do).
When I had a minor medical procedure scheduled that would require light sedation, I thought to myself, "I need a way to get there and back." I was going to call a regular taxi, and then I realized I'd been seeing this Green Cab parked in our lot a couple of spots over from mine.
I had a feeling it might be one of my neighbors, because I'd often seen Ethiopians driving Green Cabs.
So I left a note under the windshield wiper: "Hi neighbor! I see you drive a cab. Would you happen to be available on such-and-such a date and time to drive me over to San Jose and then back a couple of hours later?
He called, we made arrangements, and we sure had a lot to talk about between Ethiopian coffee and food and life in general.
You never know what kind of connection you may make with someone who is "just a taxi driver."
Even a couple of years ago on a business trip to Spain, the guys at the company there had a taxi driver they knew who they got to take me to their facility. Then I just organised with him to pick me up each day at a certain time when I paid. Beats me having to get the hotel or the company to keep having to call for cabs and beats him having to wait for fares.
Finally, I'm very surprised that you can't imagine somebody being rude to a low-wage worker...
People... talked before phones were invented?
Why is it so hard to imagine that the guy from the car service you always use might exchange some small talk when he drops someone off? Sometimes a friendly relationship develops between people who regularly interact
Perfectly sensible service to out-source and something that you want to work each time or have responsibility to arrange someone else to do same thing.
Heck, one of my neighbours is a taxi driver, and Im not in the office very often maybe 1 or 2 days a week, so for me having him drive me is cheaper, faster and less "Viral infectious" than paying for the commute on public transport.
I've arranged for him to pick up and deliver everything from people, dry cleaning, and packages in a pinch.
One thing about Dublin taxi drivers, they love to chat if given half a chance.
(Also it might have been a "car service" and the term taxi was being used a bit liberally there)
