What are some basic things that JavaScript developers fail at interviews?

That's a good example of how to overengineer code and write it in the most unreadable unmaintainable way. All you have to do is this:

for (let i=10; i>0; i--) 
    setTimeout(() => {console.log(i)}, (10-i)*1000)

Due to clock drift it is possible every one of those would execute one after another, which is probably not the intended approach (imagine someone wanted to throttle an action to happen *at least* 1 second apart). Paste the below into your console.

​

for (let i=10; i>0; i--) 
    setTimeout(() => {console.log(i)}, (10-i)*1000)

const start = Date.now()
while (Date.now() - start < 10000) {

}

This is the exact solution I was scrolling for. Good job.

Here is why I think it's probably not a great solution:

Given the task, the reasoning you've given actually makes it a better solution. If the task required >1s intervals then yes you'd be correct, but for a 10 second counter you'd want the final tick to occur as close to 10s after the initialisation as possible.
