Can i do LLD in Go instead of c++/java?

Golang has different design philosophy and lot of interviewers may not be familiar with it. Thus the design pattern you choose may seem counterintuitive or wrong to them if they are used to Java

It's better to invest some time to learn Java, shouldn't take long if you already have understanding of other languages.

Personally I would not use it unless the role is Golang based or the interviewers understands Go. But you can always try and find out if it works in your case

LLD is a way of designing software it’s language independent

I was legit thinking you were talking about lld linker in llvm. And was about to give an answer on that.

Edit: LLD- Low level design
