Jobaaj interview questions

Good person humble easy to medium questions were asked of java script css etc the interview is humble and good all the time but i got nervous so i got rejected but one thing i can't understand i gave 12 13 answers of js out of 15 still i didn't get the offer

I had 3 rounds one with HR, 2nd with CTC and 3rd with cofounder. The interview process was smooth, the Hr was cooperative Just some basic question about my current role and responsibilities and regarding the JD of new role
