We don't ask anything hard. For JS candidates, given [1, 2, 3, 'a'] return an array without the letter. Debug an AJAX call (the URI protocol has an obvious typo). For react candidates, implement an event handler for a button that increments and shows a value (all prewritten, just add this.setState({value: ++value}); We also guide them and give hints and encourage interaction, or if they need to think we leave them alone. If that requires too strong of nerves, uh, oh well I guess. I don't know how else to judge their technical ability and soft skills.
