"Converse like a talk show host, think like a writer,
understand subtext like a psychiatrist,
and have an ear like a musician."
This beautiful thing was said about interviewing people.
An interview is gathering information
through direct dialogue.
Before you start an interview, though,
ask yourself why before you get into the
how to phrase the questions.
Think about the reason you're there.
What is it that you're trying to learn?
A key aspect of interviewing people
is getting familiar with the phenomenon
that is called rationalization.
Rationalization is when people, when
asked about a certain situation that happened in the past,
they tend to change reality a little bit
to be perceived as good people, to be
perceived as smart people.
The example I have for this is if I have ask you,
would you throw a banana peel on the floor if nobody's looking?
You would probably say no, I don't do that.
I'm not that kind of a person.
But given the opportunity that no one is looking,
two weeks from now, you might do that.
And it's not because you're a bad person.
It's not because you don't believe in what you say
or you're trying to lie to me.
You rationalize.
You want to be perceived as a good person,
as a helpful person.
When you interview people, when you ask people questions,
look for the story.
This is the most important thing in an interview.
Ask about stories, about things that happen.
Ask about behavior.
For example, so in that situation,
you keep quiet and see what people say.
Better yet, if possible, ask to observe behavior.
If you're asking how they read email,
how they check their email, ask them to show you that.
Show me how you do that.
Ask about perceptions.
Not because you're interested in them,
but because they will help you, again,
to pull out these stories.
For example, what is the difference between X and Y?
Not a very interesting question, but it
might cause them to remember something
about something interesting that happened.
The most important thing in an interview
is something that doesn't look like the most important thing--
follow-up questions.
These will tell you, give you, a lot of insight
into what really happened.
Why do you roll your eyes when you say that?
What do you mean?
Why do you call your phone "my third arm"?
These are extremely helpful in understanding behavior.
A few don'ts.
Don't ask people about the future.
Three questions product developers tend
to ask their interviewees are, would you use the product?
Would you pay for it?
And how much you'd pay for it.
These are all very, very bad questions.
Why?
Because they ask people to predict the future.
The problem is, people have no idea.
The even bigger problem is that they
think they do have an idea, and they answer.
Another don't is about leading the witness.
Don't insert your opinion into the questions you're asking,
and then biasing your interviewees
into understanding what you're looking for
and then give you the answers that you want, maybe.
Don't intimidate.
If you stand over the shoulder of someone who's sitting
and then ask them a question, that
is an intimidating body language.
Don't do that.
That will affect how they answer your question.
Don't explain the question.
Shut up and see what happens.
When you ask a question, sometimes there's
silence from the other side.
Maybe the person is thinking.
Maybe the person is trying to remember something.
Maybe they don't understand the question.
Keep quiet.
Your intuition would be to explain the question.
Don't do that.
Just wait a few seconds and see what happens.
People will fill in the gap.
And finally, don't ask for feedback.
This is another very popular thing
