Just clarifying the question here. Are you asking what percentage of applicants are rejected for soft-skills compared to Leetcode performance?

To give my best shot at this, I think I read that the behavioral interview at most big-tech companies had a pass rate of 90%+. This has given me the impression that if there aren't any blatant red flags (explicitly disrespectful, lied on resume, etc) then the majority of the decision will be placed on Leetcode performance. Most companies have an interview slot dedicated to behavioral questions, however Amazon has every interviewer do 10 minutes of behavioral questions which increases the chance of one of them finding something they don't like (with 4 more chances)

That being said, I would say that there is a component of soft-skills in Leetcode performance. This is less about "tell me when you were a leader" but more on a communications side of things. It's important as engineers to be able to effectively communicate ideas. This means that even if you can code the craziest Leetcode hard problems, if you can't convince the interviewer it works or they don't understand the solution, they would view that as a negative signal in a Leetcode interview. If I had to put a percentage on it, I would say 20% of the interview would be on how you communicate it. However learning the algorithms and problem solving is the majority of the challenge.

One caveat, I'm giving this opinion on the SDE1/SDE2 level. I imagine it's different for more senior and manager roles.
