Why do some companies just send emails to invite interviews after submitting resumes? Can such a company be trusted without a telephone?

Many companies only send emails, and some simply send text messages to invite interviews. In fact, by sending information in this way, you can understand the company more intuitively through online inquiry. If you make a phone call, sometimes it may be inconvenient for you to answer it, and he said that he is a certain company, so you may not hear it clearly. Just check the company. If everything is all right, it will definitely be fine. No matter how he asks you to give it (except health certificate).
