I've found that some companies when they interview they send you a challenge that doesn't represent a real world scenario and it takes a different type of skill than real world skills. If that's the case the only way to get better at it is by practicing, do leetcode questions and refresh your A&DS knowledge. If the challenge was a real world scenario and you failed maybe was in an area you don't have much experience with. That's normal, nobody nails the 100% of the interviews they give.
