This is interviewing 101 though: establish a report with the interviewer if at all possible. If the interviewer tries to be a buddy that is in your favor to go along.

That's actually how I conduct interviews. It's been immensely successful at weeding out candidates within 5 minutes; although most interviews are 45 - 60 minutes. Basically, give them less than ten lines of code, ask them what it does, where are a couple bugs, ask what would you name the function, etc. Then we talk about how to improve it. I'd say, less than 20% of people I interview pass. It's actually amazingly low…

Indeed, it's amazing how quickly people reveal themselves in this way.

No whiteboards, no quiz shows, no grilling of any kind needed. Just: "tell me your story".

I'm not sure about introverted. I am, but when I get excited about a topic, I can be as loud as the next person. As long as I feel I have something to contribute, that is. I can rant for two minutes straight and then suddenly and unexpectedly shut up when I've made my point. People are sometimes surprised and ask why I suddenly stopped talking. I'll answer: "I've made my point."... :3

So my bet is on error avoidance.

"You are not buddies, you are interviewer about to decide whether they get hired. Many people shutting down might mean that they are not comfortable juggling "buddy" social role and expectations and "serious job interview" social expectations simultaneously." Very good point.

Right -- you don't need the "act like a buddy" part for this technique to work.

Some companies just love fast-talking engineers because they sound like they know what they're doing.

Some engineers spend a lot of effort trying to project a specific image of themselves at the expense of bringing up the morale of others in their team.

On a few occasions, I've seen an engineer tear apart the work of another engineer at a team meeting in order to make themselves look good and more senior in front of their boss - Often, the critique is delivered with such vigour that it sounds rehearsed. I've seen this behaviour in startups mostly.

Judging by this graph in the article, and somewhat counter to the claim in the article: https://plot.ly/~aline_interviewingio/952.png?share_key=Htks...

Looks to me that interview length is correlated with success rate. If your interviewer stops before 60 minutes, there's a bias towards successful interviews. It seems like the interviews that end up being "no"s tend to get hard-stopped right at the 1-hour mark.

I don't know if the following is what the GP meant, but: I've often had the pain of dealing with people who try to do it all in their head. Sure, one or two are good enough where it's not a problem. The rest of them? They keep getting confused and making mistakes. For things that are not very complex. If they had only written it out or drawn on paper/board, they would not get confused. It's most obvious when I try ex…

I have sort of the opposite problem with a coworker. This coworker only wants to talk through things and doesn't want to work them out on paper or a white board. The problem is that I can understand/remember almost everything I read, but have almost no ability to comprehend things that are being spoken (I suspect people are talking faster than my ability to think and parse what they are saying). I've talked to him ab…

I know the type of person. I usually can't follow them either (less about them being fast talkers, more about them being bad at explaining things). I found myself to usually only half-listen to what they say, and letting the other half of my mind to reconstruct the problem independently by itself. Sometimes I fail, and then I need to ask them to repeat what they just said. Other times my mental model is spot on, and I can find their problem quickly.

"They think in their head, don't work through the problem at all."

Those are independent clauses. Just because the individual is not talking out loud, should not be indicative that they aren't working through the problem. Personally, I am a very visual thinker and layout visual models in my head for problems with high (3-5d) dimensionality that would take longer to draw clearly in 2D space while explaining all the traversals I'm mentally making. I would then reduce a solution, and explain that, or I apologize for zoning out.

It became obvious to my office mates when I was working through and reducing a problem space, because I would "hang" on the thought. Sometimes I would be down, stuck in thought, for 15-30 seconds and according to them they could tell because my face loses emotion and my eyes flutter about.
