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.
