Tokio Marine HCC Front End Developer interview questions

Met two faceless individuals on MS Teams.... so far so good; however I felt like I was the only one prepared for this interview. Both interviewers were very professional...both they both had Systems/ architecture backgrounds; which is great. Except for when none of their questions had anything to do with FE development; and apparently their lack of preparedness protected under the broader the candidate's knowledge the better umbrella. But that only makes sense when combined with FE development. They're only asked me questions based on what they knew, and not based on what I should know, and that's the problem, in my opinion.
