So I’m looking at a senior dev role, and wondering what kind of coding challenges to expect, what have some of you more senior devs had to face in the past?

In what language/s?

We've been interviewing for senior developer roles over the past few months, but rather than focusing on the coding challenge itself, we've been looking at
- the approach to problem solving (does it make sense, regardless of whether it's right or wrong? Can the candidate articulate their solution?)
- architecture (we usually give a small case study)
- git/vcs practices
- tests implementation
To name a few

@encore yeah same here when we interviewed for senior position.

Also code review test, and if is js position I always expect a senior to know big O notation

@donnico
it’s for frontend web (css, js) + Java backend, although language matter much, as most scenarios could be ported to other language sets.

@C0D4 check that big O notation and algorithmic theory. A lot of senior js dev learnt on the field and is not acceptable that they don't know the basis of the craft.

@encore
Ah so more the how to rather then the can do.

Does coding in notepad count?

@C0D4 at my current job I am the lead dev and interview candidates for senior positions, want to have a "demo interview" to practice? (mostly JavaScript tho, my Java skills are rusty)

Never stop learning is probably the most important one
