Just basic knowledge of multiple languages won't work for long.
You see it's like a real-world mechanic.
"Can repair every car - specialized in Ferrari engine"
I believe same goes to us the Software engineers.
Recently, I had the chance to Interview Azat Mardan and he gave one very important tip.
"Learn multiple languages but master at least one"
If you consider me. I know/coded for a while in following languages.
But if you ask me what is one thing you are master at. I would say Node.js and then C++.
Hope it helps!
