I do. I just verify. They can also use Firefox or any other browser's tools if they are more comfortable. We are not hiring junior devs, and even if so I would still probably ask. But experienced front end devs should know how to use a browser's debugger. Like others said, it's a flag that they potentially don't have problem solving skills. I mean, if they put a single console.log near what they think is going wrong…

Ah, that's good to hear. Sorry for the rant, and for interpreting you in the most negative way. As I've mentioned downthread, I've just annoyed with silly, definite, interviewing questions that's more like a trap and less like a discussion.

Yep. This sounds like a trap to me. But OP sounds like he's not using it that way. Phew.

If I were asked to do it on my own laptop, it might be way more obvious for me to set up some watches or debug certain lines right from VSCode which I already have set up to integrate with Chrome debugging. That's how I most often debug. I've never learned to use those tools on Chrome directly because it's way more convenient to set a break point from my editor. On someone else's laptop, I'm going to reach for console.log because it's a tool I know is there no matter what the browser and what the dev env is on a stranger's laptop.

I've worked really hard to never use anything that could be a trap when I am interviewing a candidate. I'd rather do a sort of pair coding for 30 minutes and collaborate on solving a problem together.

Chrome developer tools is just a godsend. Its so much better than any other debugger I've worked with, and miles better than firefox debugging tool I personally use a chromium based browser called slimjet to do all of my development. It runs off v55 I think which is like 5 versions behind chrome. But its nice to have a dedicated app for debugging. One tool that I find I use everyday is this: http://lab.maltewasserman…

FYI v55 is quite old by now... a quick check at chrome://version on my Mac shows that Chrome Stable is running v67...

Can’t you just ask them if they have experience with the Chrome debugger? And if that’s such a deal breaker for you, you can teach them in the first week? I mean, it’s not like the Chrome debugger is such a complicated beast. Even if you have no experience with it, you can probably learn 90% of the useful tricks in a few hours.

But if they don't know how to use the Chrome debugger then that probably correlates to not being able to do many other tasks. That few hours just teaching them how to use Chrome debugger turns into weeks of teaching them how to do lots of tasks. I have nothing against teaching new hires but for some businesses it is a significant cost so it makes sense to weed out applicants that won't be able to get stuck in straigh…

I don't know Chrome debugger because one of the first things I did was to get VS Code to control Chrome debugger so I can set breakpoints while looking at code with the font and highlighting I'm familiar with.

Weeding out applicants is dangerous if you're not trying hard to disprove first impressions or wrong answers.

to be fair, chrome's versioning means that that's probably just like 2 weeks difference.

I implemented two simple interview tests in order to weed out people who can't do simple debugging. In one, I hand them my laptop and give them a basic create-react-app sample that uses fetch on a remote URL, but there's a typo in the URL. I tell them it's supposed to fetch a remote REST API and parse the JSON but it doesn't work--how would you fix it? So far, two ways to pass: Just look at the source code, or use th…

Lol, depending on the typo in the URL, I would probably think the service is just down, and it's not part of test.

Give the developer a simple task that is work relevant and 24h. If the person does it in 5m using some fancy trick, then you know they're a problem solver of high calibre. 1h-5h: They are probably adequate. 24h: junior or bad. Ask them about the trad offs they made. The 24h guy may not have made any, and may be the perfect maintainer. The 5m guy must have made some. Ask for their reasoning. It may be the reason to hi…

How do you know how long it took? Even with the fancy coding screen sharing software? I could have had an important phone call and walked away from the laptop.

Chrome releases about every 6 weeks, so the difference is about 1 years worth of updates.

This is correct. More info here: https://www.chromium.org/developers/calendar
