Is it credible to send a message to inform the interview by SMS?

Generally, the formal interview notice is email+telephone notice, and some HR will send the interview location and bus route to the applicant by SMS.

If you are not at ease, you can check and confirm two points:

1. Did you really send this position yourself?

2. Call the human resources department of the recruiting unit for confirmation.

If the above two points are confirmed, you can rest assured.

I hope I can help you. Thank you for your adoption.
