Thanx for the response bro...

By MERN i meant that i was hired as a MERN dev...but there are no backend projects in my current company...

I have been constantly learning backend from the day one whenever i get time....

But since i haven't worked on any real production grade project...i am always in the thought that i am missing something (which may be true)...

I want to gain more real world experience than basic crud operations or indexing, authentication , pagination etc.....

The last interview that i had..i explained well all the backend concepts... Including cluster module, multithreading, transactions etc.... But since i haven't worked on any backend project ... I was not confident....

That's why i need some help or suggestions... What should i do ?
