That is called imposter-syndrome, and it basically is the opposite of bullshittery. All of us have insecurities about what they do -- our field is concerned with very abstract concepts and at the end of the day you have produced something of value (lines of code, a build system integration, maintenance on a legacy system), but you cannot touch it, feel it or have any relationship to it other than intellectual satisfaction. This can lead to a valuation problem, where we find it hard to put a value on the work we actually do. We suddenly begin to doubt the whole process and our role in it. Its not unusual in tech, really many of us have the exactly same thoughts. >> "the people who work at [X] are probably better than me" Yes, some of them probably are. And some others are incompetent idiots. But most of them are neither here nor there and good percentage of them are asking themself the very same question (with X = {microsoft, apple, nasa, you name it...}). The fact, that you are able to reflect on yourself, "can pass technical interviews" and "code for fun" is a good sign that you are probably not a bullshitter.
