1. You don't need to attach a certificate, but it's best to list the certificates you have in your resume. If there are many certificates, please select an important column. Certificates can be divided into academic certificates, skill certificates and honorary certificates. You can make a copy of all the certificates, put them in one and bring them with you during the interview.

2. It can be sent as an attachment or text. Look at the company requirements. If you are not at ease, you'd better send it in both forms. However, if you send text directly, you should read the format again after copying your resume to the mailbox, because copying the past format will be disrupted.

3. Pay attention to the name of your resume and email, preferably including your name, the position you are applying for in XX, and the number of words in your resume. It's best to leave your mobile phone number on your resume. If it is a foreign mobile phone number, add zero before the number. Because the company will contact you directly according to the number left in your resume, if it is a foreign number, the company will dial directly to display the empty number, so you are likely to lose the opportunity.

If the company doesn't reply to you, it means that there is no news for the time being. The company will choose according to the content of your resume, and if they think you are suitable for this job, they will call you for an interview. Generally speaking, if there is no news for more than half a month, you don't have to wait. Of course, if the recruitment process of some companies is complicated and busy, and there are many applicants, the response time will be longer.

If there is no news after waiting for a while, you can call and ask. On the one hand, it can confirm the situation, on the other hand, it can show that you attach importance to this job, so that the applicant can give you a little impression.

I am in personnel management, and I hope I can help you.
