Rails Developer Interview Questions

841 rails developer interview questions shared by candidates

This was a pair programming session with a Ruby engineer. They allow you to use your own laptop which was great but you only get 30 minutes to finish the problem with working unit tests. I think they re-use this pair programming problem so I'm not going to divulge details here. But it wasn't a particularly hard problem, they just want you to see how you code and test. Do not forget to write unit tests! Ideally you would develop it in a TDD fashion.

100 test questions, no calculators allowed, several misspellings on the test form. Catch 22 questions. The knowledge based test that is more for passing a test than being able to do the actual work. Knowledge of Ohms law a MUST, knowledge of Math a MUST. I would say, they would do better interviewing, THEN testing candidates, I was there with quite a few very experienced people that felt they did not pass, makes me wonder who got to move on, most likely someone good at math, not mechanics.
