Job with only JLPT

So recently i saw some guys online claiming that if you have JLPT N2-1 so there are chances that companies will hier you and provide OJT(On Job Training) and they also got through same method in 2-3 months by approaching companies like crazy on LinkedIn, indeed, etc. Some articles on google says many japanese companies provide OJT.

So i want confirmation if i clear JLPT N2-1 and approch companies just with the JLPT certificate. Is it worth it or possible approach??

I'm aware of certified skills + jlpt but I'm asking just JLPT approach.

Thank you
