2 day long interview that throws you immediately into their codebase, but it is seriously gutted and the specs are therefor fragile. You’re asked to write a simple join model and then a more complex filter feature inside a Rails application. Not a lot of guidance and it assumes you understand their business model and how the app is designed (even though you don’t get the full codebase). No questions about career development, past experience/projects. I didn’t feel they took much interest in me as a person - just whether I could do their test. It was a very one sided interview.
Stranger is that this was for an engineering manager role but they asked no questions about management style, how you grow teams, mentor, hire/fire, etc. It felt like they were interviewing for an IC role. When asked they said that all managers start out as ICs at first.
