No, don't worry! There is a row of fonts next to the resume. If you look carefully, there is a column called "Resume Read". If it is "read", it proves that the other party has read your resume. The landlord had better not vote too many times, it's unnecessary, it's not good to be afraid of the other side's annoyance! When submitting your resume, there is a button to check whether you have submitted your resume to this company. If you forget it, you can click it. It's safer. I wish you a successful application!
