I would have started by getting a behavioral read on the interviewer when I walked in the door.
By the time that he/she asked me to sell them the pen, they would be selling it to themselves with little effort on my part!
It is important that you focus on what the interviewer is wanting from you. Get a sense of what the interviewer needs to hear in order to want to purchase the pen. Maybe it is the features of the pen and maybe you should describe how the pen can be used in everyday life to help make his life easier. The interviewer will say, i don't need a pen, i have a computer etc. You will need to figure out how to work around technology and make him understand that a pen is necessary even as the future progresses and writing utensils become more obsolete.
Sell them for the pen. Imagine they have a check for a million dollars or lucrative contract and they don't have a pen, also a minute to sign. What will they do? Buy a pen from you now!
I am Sorry I need to ask a Question are you in Sales or do you want to be in Marketing?
You sell it in opposite directions with an emphasis on the other?
If you can't do than Sales and Marketing is not your strong suit, maybe you should be in support get an accounting degree or be a visionary or just a high paying actuary. Good luck!
ask the interviewer for a signature, then when they ask you for a pen, tell them, "supply and demand!" See "Wolf of Wall Street!"
create a need, or desire, then offer a solution
I would ask, "Why would you want to by that pen" they would tell me.
I would ask, "How would owning that pen help you" they would tell me
I would ask, "what would you be willing to pay for that pen" they would tell me
I would say , "SOLD"
First I would ask them how they heard about me and why they decided to stop in today to see me about their pen purchase. Then I would I ask them if they had given any thought about their pending purchase. What type of pen are they in the market to buy? What functions are most important? Is their a specific style or color? How much writing in a given day do they plan to do? What do they do for a living? Is comfort while writing important? Lastly, I would ask them when they needed to make their purchase. If I have a pen that will meet all your needs we have been discussing, will you purchase from me today?
If yes...you have a slae. If no...keep closing. Questions, questions, questions!
How about this scene from the Wolf of Wall Street:
As an interviewer, I am looking at your sales style. Are you going to ask me questions about what I look for in a pen or are you just going to feature dump. I want you to listen to what I'm looking for and explain how the features benefit me according to what I look for, and don't forget to ask for the sale and close.
The question is to make sure the interviewee understands how to sell such as offering benefits instead of features. Demonstrate that you understand the question and give a good answer that you understand the basic principles of selling.
Interviewer: "How do you sell this pen."
Candidate: [takes pen]: "Can you please write your name?"
Interviewer: [Asks for the pen]
Candidate: "Ya I can sell it to you for $X"
