I understand what you mean. But the personality properties like agreeableness, extroversion, openness, should reveal themselves through behavior over time. Otherwise, what's the point in them? And, say, hi-tech work seems to provide enough opportunities, say over a year, to reveal all of them. This is what I meant by "contact".

Besides, have you not heard the "we do not spend enough time together" idea from a spouse? Not to glorify it, nothing good about it, but it seems to be the reality for more people than it should be.
