Timid people are afraid to ask what to do when they see the recruitment, for fear that the position they are recruiting will not work.

I think what you need may not be knowledge and ability, but courage and confidence.

If you want to find a job, you can ask and answer when you see a recruitment opportunity. Don't hesitate to shrink back. If the answer is not good, or the other party is not satisfied with you, you may just not be hired, and there will be no other losses; If you answer well, or the other person is satisfied with you, you may get the job.

Therefore, I suggest you work hard.
