This is probably the biggest piece of non-advice in the entire article. Feeling is bullshit. If I had followed this advice throughout my career...
I've been introduced to people who I'd instantly hated but a weeks later had become my best mates and I've been introduced to people who I'd loved at first sight (oh, so social, funny and well spoken..) and they turned out to be completely useless.
It often takes time to get to know someone, don't let a first impression be a lasting but judge on the second, third and forth instead. You'd might be missing out.
It's not about first impressions - it's about people you have a bad feeling about but work with anyway because you assume it's going to be worth it. Don't do that. That's not what you're describing.
It's exactly what I'm describing, I've worked with people in the past who I'd initially greatly disliked (i.e. had bad feelings about) who then turned out to become great friends.
I have learned that little things in a start of a relationship will multiply over time. If somebody is just a bit dishonest early on, the relationship might explode in a couple of years due to lack of trust. With the people who have the same core values as me, I have the best long-term relationships that are good for both of us.
