From my experience, having top-tier CS skills is definitely a harder requisite than being a "likeable person" in the hiring process. Yes, companies are looking for culture-fit and making sure you're not a total weirdo, but hard skills will always trump how sociable you are.

Additionally, "getting shit done" is very hard to measure unless the company is asking for contract work before extending an offer (which is rare) - so it again comes down to lots of technical questions which test your CS and language-specific skills.
