Find a Genuine Weakness:

Don’t use a generic weakness like “I’m a perfectionist” (which is overshadowed and unconvincing).
Choose a weakness that is relevant to the job but does not significantly impact your ability to perform well.
Consider the weaknesses you are actively attempting to improve.

Ex:

Since I am a recent graduate, I am still gaining professional experience in the job market. While my academic projects and internships have supplied some useful knowledge and abilities, I realize that there will be a learning period when I started a full-time job. I’m a quick learner who is eager to contribute, and I see this as an opportunity to develop immediately under the supervision of skilled professionals like you.
