One pro-tip: you can hack your own mind to work better in these situations by shifting from thinking “OMG why are he/she so stupid for doing X or Y, I would do it better” to “He/she are clearly stupid for doing X or Y, let me use my superior brainpower to guide them to achieving their goals even if they can barely understand/explain what they are trying to do”.
They’re asking not for the info, they are asking to see how you communicate (ie “soft skills”). Your response immediately demonstrates that you do not like people, are probably a PITA to interact with, and will have a hard time collaborating with any other humans who do not think exactly like you do. The good news is that soft skills are skills, and as such they can be learned and improved on.
Go has a much cleaner syntax, and is better suited to its specific niche which is (relatively) low-level BE development. If you are attracted to that niche then Go is an excellent option. Also, Go is almost a default for developing for K8S, which might be another plus.
On the other hand, JS is a more general-use language. It has a very loosey-goosey syntax and lots of weird behaviors. It is applicable on both FE and BE but be aware that in each of those, knowing JS is just a first step, since (for example) for FE development you will also need to know at least one of the major frameworks (React, Vue, Angular etc) as well as the page object model and a ton of other stuff.
Bottom line- usually the language is the tool, not the objective. Figure out what you want to develop, then choose the optimal language to do it with.
The system is rigged against you. Any “gameable” aspect of the system which could be used to even the playing field is either regulated (ie you need a specific license) or billed in such as way to make it unprofitable (or at least transfer all the risk to you).
