Job switch as an Angular Developer

Hi people, I am looking for a jab change. I have 3 years of experience as an Angular developer.

I have given a couple of interviews but couldn't clear. I get really stuck on technical round. It's like I go blank in front of the interviewer. I know that I can solve the problems but I just get too nervous.

I have good working knowledge of Angular. Please share any tip or thoughts on what should I do. I really need to change my company.
