Is it relevant to the role? Has someone in that role/with that title performed that type of work in recent memory? If so, it's not dated.

Now I'm really curious what kind of answers you're getting. If literally nothing, sounds like this is a great filter (but also makes me wonder what kind of candidates you're choosing to talk to).

Is this one of those file under (pun intended) Gen-whatever doesn't know anything about files or filesystems because of their iphone/mobile upbringing things?

dang maybe I should pivot into data engineering. I'm great at that stuff. What is data engineering?

If nothing else would assume they have used GitHub or say 'drop it in teams'. Even if they have only ever used the cloud there is send a link from my Google or One Drive. My first answer would be FTP or rsync. Maybe they are over thinking it and assume they need to get it on another machine without the owner knowing about it IDK. Maybe it needs to be reworded. Or follow up if there is no answer and say how did you turn in your homework to the professors or think about how you collaborate with other developers on a project.

Maybe phrase it with a bit more specificity. "How can you transfer a file between pipelines", services, etc.

> I can't get anyone in an interview to answer this. I never get sftp,scp,rsync,email,usb,nas or s3 buckets/gsutil. Nothing. Nope.

They literally don't respond at all? To be fair, I'd presume it's some sort of trick question, but a few follow-up questions (how big is the file? are there any security/privacy/etc rules involved? is there something else unusual about the computers (and are they local "machines", cloud VMs, etc)?) would resolve that quickly. Here I am practicing brainteasers and leetcode and I could get ahead by knowing you can send a file in an email.

I suppose some people might freeze because it's so vague and they're wondering what you're getting at. Personally, I'd say, "Well, in most cases I use rsync or scp, but it depends on the situation."

Then I'd tell the story about how one time in the mid-90s I needed to transfer a huge (probably 100MB at the time) file between a Unix system and a Windows system in our office. After FTP, Samba, and a couple other methods ran painfully slow for unknown reasons, I discovered that a DCC in IRC flew at top speed.

But I'm not desperate for a job and trying not to say the wrong thing.

Something bothers me about these questions. In the real world, when you're solving a problem, you have so much context. These questions are like waking up from a coma and you're in a video game and you don't even know the rules.

Obviously in the real world you need to ask follow up questions sometimes, but you have at least some context for orientation.

Sounds like a great weed out question if part of the job is moving data around.

Seems like a great filter.

A while ago I was interviewing candidates for a senior frontend position. My filter question was to explain how to make a progress bar. Most candidates couldn't do this, one said it was "not what they were expecting" and that they were just expecting leetcode problems.

(for non frontend people, it's just a styled box in a box....)

What do they say when you ask?

Not dated, but with zero context like that, I'd assume it was a trick question trying to see if I can come up with types of scenarios where sneakernet outperforms digital transfers.

Do people not start asking questions like, over what medium? Is there direct ip connectivity or nat/a firewall in between? How longs the link? How big is the file? I would try and set some parameters if people are not or are struggling.

I would answer it like this:

For a Linux user, you can already build such a system yourself quite trivially by getting an FTP account, mounting it locally with curlftpfs, and then using SVN or CVS on the mounted filesystem. From Windows or Mac, this FTP account could be accessed through built-in software.

data engineering doesn't do data transfers... different subjects altogether

Seems like a fantastic filter question to me. It's basic, it's not an unfair or trick question, there are multiple valid options that the candidate can respond with - you're not fishing for your single pet solution - and a strong candidate could demonstrate ability by going into more depth and mentioning multiple options and explaining when one option would be preferred vs others. Keep asking it.

If you're seeing a high rate of candidates who can't answer it at all, that suggests that the population of candidates who are applying for your roles are really poor fits for the role.

Maybe worth exploring if there's ways you could change how the roles are advertised to access a different population of candidates, or perhaps ask this basic question earlier in your hiring pipeline -- e.g. as an automated screening question as a pre-req to interviewing with humans.
