When submitting your resume online, you should generally read the requirements before submitting it.
Some companies don't say don't call, you can call and ask, or you can call and say you want to visit the company and ask if you can visit the company and meet and talk. Depends on what you said on the phone. Some companies explicitly say that if there is no telephone consultation, don't call.
Some companies don't update the information published online for a long time, resulting in many resumes being ineffective. Therefore, I suggest that when you submit your resume online, try to make it more detailed and highlight its characteristics.
It is best to go to the company to find a job, so that not only the two sides can feel each other intuitively, but also they will be more sincere.
