-My personal belief is that any DevOps engineer should know coding, at least to some degree. Having this skill you can automate manual processes, improve some of the open source tools you are using today or build new tools & projects to provide a solution to existing problems. Knowing how to code =  a lot of power.

-When it comes to interviews you'll notice that the level of knowledge very much depends on the company or position you are interviewing for. Some will require you just to be able to write simple scripts while others will deep dive into common algorithms, data structures, etc. It's usually clear from the job requirements or phone interview.
