InterviewVector Sr. Frontend Engineer interview questions

InterviewVector was an external screening partner for one of the companies I was interviewing for. The Round scheduled was titled: "ReactJS + JS Fundamentals" for 90 minutes. Don't bother about title or anything there wasn't a single react based question. I was able to get a reasonable solution for all the JS questions yet the interviewer. The interview was unprofessional, and non participatory. Interviewers need grow up and get out of school teachers mentality, and looking into documentation and validating code before implementing is called being thorough.
