I know what you mean, but given the context of a job interview, by definition[1] you are in a lower power position.
I agree with sibling comments, though, that respectfulness is not mutually exclusive with alpha-ness. And if in general you are a respectful person, a high-power posture will probably not impact their opinion of your respectfulness too much.
[1] Assuming you really want the job and unless you are a hot shot who is gracing them with your willingness to work for them.
Although you're partially right, I wouldn't say you are necessarily in a lower power position. They want to hire you (assuming you are up to snuff) just as much as you want to be hired. Assuming an "equal-power" position shows you believe you are capable of filling the role, and deserve it. It also suggests you would be perfectly okay with NOT getting the job if it doesn't work out.
I've gone into every job interview I've had with the attitude that I'm a hot shot who is gracing my employer with my willingness to work for them[1]. I've gotten offers at about 50% of them, which means that I've turned down more companies than have turned down me.
Confidence really does work. If you sincerely believe in your abilities, it's much easier to convince others to believe in them.
[1] This is not mutually exclusive with respect or humility. It's quite possible to believe you have a lot to offer your employer while also believing they have a lot to offer you, and then the job interview process is just a matter of negotiating the right fit.
Interesting. Whenever I see aggressive confidence in an interviewee, I immediately think Dunning-Kruger because statistically it's by far the most likely cause. Either way it's down to empirical evidence though.
Anyway, as far as anecdotal evidence goes, I tend to intentionally give off a pretty neutral vibe and rarely worry about flunking an interview. (I chalk it up to mad skillz rather than body language though.)
One could also argue that your willingness to quickly diagnose an individual coping with a traditionally high-anxiety situation (interviewing) with trendy cognitive bias issues calls your ability to recognize your own weaknesses into question.
I don't think a job interview puts you in a lower-power position by definition, though I admit that there does seem to be a lot of social conditioning to make people believe this is always true.
The power dynamics depends a lot on the specific market conditions at a given point in time. If demand is low and supply is high, you do have a power disadvantage, but its just as possible to see the reverse where the employer is at a disadvantage.
The typical HN reader is more likely to be familiar with the latter than the former. Not because we are all hot shots, but because our industry is presently in high demand and has a low supply of labour.
I agree with sibling comments, though, that respectfulness is not mutually exclusive with alpha-ness. And if in general you are a respectful person, a high-power posture will probably not impact their opinion of your respectfulness too much.
