First of all: express your design style concisely, not too artistic, and hit the nail on the head. After all, HR only spends a few seconds browsing everyone's resume on average.
Secondly, put forward a successful case of your design, or put forward a work or idea that you have no work experience but won recognition, so that enterprises can see your potential and value.
Finally: highlight your strengths and the reasons why you are more suitable for interior designers than others. If you have hardware conditions, you'd better write them down, such as education, works, etc. Some enterprises still have an inspection of the starting point and professionalism.
Finally, I wish all the best and all the best.
