I have seen that. I also seen people openly talking about social skills being opposite of coding skills and literally making implications about others. I have seen people pretend lower social skill then they actually have.

The most common through is assuming that someone with bad social skills is genius in coding with zero grounds for it. Without seeing code or even talking with those who know his code closely, anything like that. Assumption was that that those people are better in coding because got knows why. I suspect part of it is wish to compensate, but part is stereotype.

Open offices have nothing with it, except making people with poor social skills more actively annoying. Which can cancel some of effect I guess.

Not long ago, I failed two sql whiteboard problems and passed 2 c# problems. I was informed by HR that they are making me an offer based on my great people skills, even though I failed their SQL quesitons.

I sucked at white boarding(still do because I don't like grinding leetcode before interviews, and I usually make it known). When I first started interviewing I needed like 10 minutes to come up with palindrome solution even though I did it in school so many times. That time I also received an offer.

Now, that I think of it I my success rate is 75% and that includes a fortune 1k company. However, it is a pretty small sample size. Now, that I think of it I need to interview more.

Very true. Back when I was trying to become a dev I'd show up in a suit and try to be as socially pleasant as possible. When I started dressing more sloppy, not shaving, etc. and being slightly more awkward (mimicing the interviewer) I actually started getting offers..

I think that fits into 4 more than 8. You have good enough people skill to recognize that you're different than the interviewer, and then putting up an facade to convince them you're like them.

People with poor people skills incidentally act similar to other people with poor people skills. People with good people skills can choose to act similar to people with poor people skills.

I feel like they might be referring to peers here rather than management

Given the author's name, I think she's female. I fear that, for a female, #8 is more likely to be true than for a male.
