Much of it might be down to perception and expectations. If you expect people to be unpleasant you are more likely to interpret their response that way. If you expect a certain response and you get a different one, you may take things as personal, directed against you rather than just a neutral response. If you are happy, you may interpret the same interaction differently than if you are sad, angry, upset or in a neutral state of mind.
For example, the interview example you are giving.... I have been on both sides of the interview table. The way interviews are conducted at my workplace is called 'competency based interview' - if asked about my achievements, I might for instance respond that we did a, b, c, with this and that result. The question what have you, personally, done, what was down to others would then invariably come. It's not condescending but trying to figure out what your role was in that achievement.
This is not to dismiss or criticise your experience. Just a pointer to a possible different view. We all get conditioned during our lives in how we relate to situations or other people. And in a sense that is karma. Personally, however, I see karma not as fate but as starting point to take control of my life. What has happened is gone, nothing to be done about. What I do today, in this moment, however, is entirely my responsibility. I can change anything in my life. It may take time. It may be difficult. But it can be done. And so my future changes too. And that, too, is karma.
