FWIW, I've had good success with these two approaches: * code review: Screen share with the candidate a small code snippet in a language/framework that they are comfortable with that needs improvement. Have candidate talk through what feedback they would provide in the context of a code review to improve the code. * code pairing: Pair candidate with an engineer on the team to improve some existing code (add a simple feature). Both of these approaches have been very helpful at understanding how skilled a candidate is, how familiar they are with a language or framework, how they provide constructive feedback, etc. Code snippets can be designed to encourage discussion of security practices (SQL injection, for example), capacity planning (5 transactions/day, /hour, /sec?), algorithmic complexity, etc.
