Can I send a text message to thank you after the interview?

I'm HR, which is generally unnecessary. If the company thinks you meet their requirements, it will accept you. HR who do signboards are generally busy and don't even have time to read a lot of job resumes. Even if you send an email, it is often ignored, and there is no need to write it by hand. If it doesn't meet the requirements, it's no use doing the most.
