First time I used it, I had not written a line of Go prior, I rewrote our data ingestion gateway from Ruby to Go. It took me 1 week, and it had full feature parity. I don't think I had the GPA at university to land a fresh grad job at Google.
Sure the tooling around it (besides the compiler itself) was the dumbest 21st century tooling I've seen (this was ~6 years ago), but it was quick to learn, quick to write, quick to compile and quick to run so who am I to complain.
It had this weird system where all your projects were supposed to be located in one directory structure that mapped to their git namespaces, it made no sense at all and was a pain to work around.
