Are These Coding Practices Common in the IT Industry?

I recently started working as a Java developer for a small foreign company. Although I was hired as a software developer, a lot of my work involves DevOps, which I'm considering leaving for.

However, one thing that stood out to me is my supervisor's coding practices, which I find unusual:

1. No-comment coding practice: He insists that code should be self-explanatory and that comments shouldn't be used at all.
2. Using var types everywhere in Java: He's completely against using strong types.

Are these considered industry standards nowadays, especially for small startups? I'm asking cause when i did my internship in a local company this was completely opposite?
