I'll think about it, don't worry. Now many companies pay more attention to ability. Besides, it's only a matter of time before you get a certificate.
I feel ok, but I suggest you find an assistant, which is more beneficial to your future development.
4. Experience is indeed an important condition for the company to consider, but if your personal ability satisfies the interviewer, you will be given priority. Assistant and other positions will soon be available. Just tell the interviewer that you are more adaptable and can quickly integrate into the work, so that your chances of success will be greater.
Finally, I wish you a satisfactory job.
