I am getting bewildered by the way the OP keeps shifting what this thread is about.
First it was about informing people of their personal attributes, then it became about claims of being discriminated against because of your height in job interviews, although no good evidence for this was adduced, let alone proof that it was a common prejudice. Now 11 pages in we have references to stereotyping, which is something else entirely.
To inform someone they are tall is not to stereotype them. It is clearly an attribute they have. To ask someone taller than me to reach for something off a high supermarket shelf because I cannot reach it is not stereotyping. Even making silly and no doubt iritating jokes about the weather, or the view over a wall is not stereotyping.
Stereotyping is assuming that everyone who is tall is good at maths, bad at emotions, for example, so suitable for a job as an accountant but not as a councellor and acting on that stereotype.
Beng asked why you think you are the best person for the job is what job interviews are all about. You have been shortlisted because, on paper, you look to be one of the most qualified (in the widest sense) for the job, now they want to meet you and talk to you to find out more about you and give you a chance to show that you really are the person they are looking for. Whether the other candidates are better or worse and whether you know that or not is irrelevant. That is up to the interviewer to decide after the interviews are complete. Your job is to convince the person interviewing you, to the best of your ability, that you are the person for the job. Sometimes you succeed, sometimes you fail.
Which brings me back to the start. Exactly what is it that bothers you about being tall?
Yes, the thread does shift around. To me that is part of following a discussion where it leads and not putting up a rigid "off-topic" wall if something interesting might be lost because of that.
Paragraph 2. I wrote about one case where I feel it happened. I did not claim it as general or even widespread. Yes, I suppose stereotyping is different from the original question, but it is related so not wildly off-topic.
Paragraph 3. Yes, thinking about it, you are correct.
Paragraph 4. Yes, that is a possible example of the result of stereotyping. As is presuming that a tall person is aggressive and violent.
Paragraph 5. Yes. I suppose the man thought something like "I need to employ the best person for the job" then asked me to say why I was the best person for the job. I suppose me replying to the literal question rather than the implied question says a lot about me. Yes, I know! Or at least I suspect it! 
Paragraph 6. Nothing bothers me about being tall as such. I am happy being tall, I like being tall. The problems are because the built environment is in some ways a scale model world and I get treated rudely or nastily by some people because of my tallness and I am sometimes inconvenienced.
For example,, I once, in my twenties, went into a shop, selected an item, took it to the counter and handed it to the lady, perhaps in her fifties, behind the counter, for her to wrap and for me to pay. Just an ordinary transaction.
"You're very tall", she said.
Oh no I thought, not again.
But then she turned to some other women about her age nearby who were probably customers and said
"Viscount whatever's son was very tall, oh he could dance, I remember ..." and she started recounting something, bobbing my intended purchase up and down in her right hand as she spoke.
After quite a while I realised that I was not going to get served and I had other things to do so I quietly left. I turned to my right after I went out onto the pavement and I looked back through the shop window and there she was, talking away, a look of joy on her face as she spoke of whatever, still gently bobbing the item up and down in her hand. Presumably she finished sometime and perhaps realised that the would-be purchaser had gone.
