Would you then consider that a plus?
To me person like that will be first to raise a hand when something is not right in the project. It might also be a good indication of goal oriented thinking, they know whats important and prioritize to achieve goal
The few times I’ve had someone do that, the last thing those folks did was (as one put it) “look for problems” by raising project issues or really doing anything but the bare minimum. A bare minimum that had to be clearly articulated several times to the several people I’ve run across - who one then specifically asked EXACTLY what I meant by ‘keep the system running’, so they could exclude a bunch of long term maintenance work from that minimum shrug
IMO, if someone is curious and cares about what they are working on, it shows, and we would never even have this discussion about them - even if they did ask about EXACTLY what the vacation policy was.
If someone starts off with asking about essential thing that is important factor for them it means that its a dealbreaker issue for them.
Whats the point of interview if they know there is no flexi time, and you only look for flexitime jobs??
Its actually a matter-of-fact approach that goes straight into details and saves everyone time. Given it was properly delivered I would be more inclined to hire engineer like that.
