Also, I ask what are the most important things they are looking for in the team they will be joining. Some people are interviewing because they dislike their current job so this is a good clue about their morale and what kinds of situations can lead them to give up and start interviewing.
By this point, after talking to someone for a few minutes I usually have a sense of whether they are easy to talk to or whether the conversation was draining for me and a notion of how smart I think they are. If both of those feel good I focus on selling the team and what it offers so they bring their A game to the in person interview.
But imagine you're at a restaurant with your team and someone orders a dish you've never tried. Do you simply decline to try a bite? Or do you try a small bite in case you might like it? I find that openness to new experience correlates highly with good problem solving skills and team cohesion.
Many group/team interactions are essentially minor culture clashes, and being able to navigate them requires being open to different points of view, etc.
I'm really NOT keen on trying chocolate-cover ants, thank you.
But why not try one ant? I'd try one.
Many groups are discriminated against (historically or presently), and members of those groups may not be too keen to open themselves up to unfair stereotyping. I've dated a girl who would never tell a prospective employer she was Jewish; she just wouldn't eat a pork dish and would probably seem evasive to you.
That doesn't even account for those who may just be squeamish or petrified of insects. Still others have embarrassing dietary restrictions.
It's hard to fathom when you have mainstream traits and limitations (it certainly was for me), but many people who consider themselves others are reluctant to give away information that could later be used to hurt them. Sadly, this reluctance is often justified.
True, I meant it as a metaphor for the kinds of new experiences/ideas one encounters day to day in the workplace.
What I'm saying is, the one-shot impressions from interviews are horribly inaccurate. There is simply not enough data, plus the measuring instrument (interviewer) is flawed also in nonreproducible ways.
A simple thought experiment: let's say I build a machine that measures confidence and ability to read the room. Would it select different candidates than you?
But, I understand that other people do like food. And that's ok.
I've tried that a few times but never really got any decent results out of it. (Disclosure: I conduct ~100 interviews a year.)
The question is too open-ended, so IMO it's akin to asking a child "what did you do at school today?". The answers for that are just non-specific and often the candidate falls back to describing what they currently do at their work. Hell, if they are interviewing for a new job, they are looking for a CHANGE, and I learned just one thing they probably don't like. Instead in preparation I go over the candidate's CV and try to gauge what kinds of technologies, environments and problems they have been exposed to. And then I pick the most interesting and/or longest ones as items of discussion.
Most of the times I find that the candidates are happy to tell about their experiences and voice their opinions. This has the dual benefit of allowing the candidates to better relax, and gives me a glimpse into what kinds of details catch their eye. The very best experiences are those where the candidate forgets they are in an interview and end up treating me to a wonderful lecture on a topic that I have not known enough about. When that happens, I always feel cherished.
