I interviewed for a front-end dev position (it was my first ever interview in the industry, I vomited before I got there so it was a pretty crazy day).
I come in. The front-end guy starts asking me questions to try and solve something he is working on. No-one else is there yet. He is asking me about why a JS compiler is removing his comments, I say I don't know, I have never had that issue before...I make an off-hand comment that I use React and most of my JS code doesn't have comments because I am just working on projects by myself, and I don't do a lot of library code...the manager comes in at this point, and proceeds to berate me about why commenting is essential. I say: I use comments where they are needed. Off he goes, again.
Interview starts. Manager proceeds to go through a series of questions designed to expose my ignorance. None of which are related to the job. One classic was him explaining to me that database normalization made no difference to the size of the database because "the data is all the same on the disk" (which is, ofc, not accurate...I tried to explain, he just kept repeating that over and over...he actually said as I was leaving "make sure you understand databases for your next interview" with a massive shit-eating grin). For some reason, there was also a back-end guy there who, upon hearing that I built something in Java, proceeded to launch into a series of questions on internals of Java (for example, he asked me what the difference was between certain versions of Java and the size of the heap...perhaps unsurprisingly, he also got some of this stuff wrong but began laughing when I said I thought X was Y).
The only two questions that I had about front-end dev were: the front-end guy trying to ask me to help solve an issue he was having (before the interview, when no-one was there), and a question about the value of this in arrow functions (which I got wrong, but is also an excruciating thing to try and explain, so I don't think the guy knew whether I got it wrong...it is a terrible question). That was it.
>He is asking me about why a JS compiler is removing his comments
Huh ? language parsers remove comments because they're comments, that's literally by definition. Are you (or your past interviewer) using "comments" in a different sense ?
(Also, not trying to be a pedant on you I swear, but technically JS is traditionally interpreted. Most mature runtimes have compilers but it's not part of the API. It's just a juvenile pet peeve of mine when language implementations are generically referred to as compilers.)

I sincerely hope from my heart of hearts that company or department is in it's well deserved position in the depths of the toilet now, or at any rate that specific person.
I actually can't remember the details. I believe we were talking about Babel...so, technically, a transpiler. Or it actually could have been one of those code bundlers (I seem to remember they were using browserify...this was a while ago but I believe most people were already using webpack then...JS...what a mess).
Actually can't find him at the company anymore. But the company isn't doing too well (although they seem to have moved into a nicer office). Revenue down 50% last year (from a small number to an even smaller number), costs up 60%, losing substantially more money than they have revenue, the operations guy who did my interview isn't there anymore either...true "tech company things". I didn't the impression that the company was that bad, they were more "much steam, no fire".

I'm really sorry to hear this, that sounds incredibly stressful. The worst part about stress in technical interviews is that even under good interviewing conditions (which you clearly didn't have) it can really hobble a candidate to be stressed.
I hope this experience (or this HN post) doesn't scare you away from programming or interviewing at software companies in general. Those guys sound like jerks. There are good companies and decent coding interview routines out there.
