I recently removed my phone number from my résumé be those HRs keep calling me without texting me first. (I do leave my email address on it)

Recently I switched to a new job finding platform, and it has a feature that allows you to send your resumes in batches. Most of the time, I don't check the recommendations, and I just yolo it. So when someone calls me without telling me beforehand, I don't know who they are... and I don't pick them up. (Yeah, I generally ignore all unknown incoming phone calls to keep way spams and promotions. If that's an important call, the other side will try again.)

Talking about the batch sending feature, I feel bad for those hardworking HRs getting spammed in this way. But from the last year of job finding experience, I spent a lot of time searching the company and decided I'd like to go there, sending messages and my résumé to them, and got no reply. This happens a lot. So to improve the efficiency, I decided to spam them and see who came back to me. After all you have to reply me before we can keep talking. And HRs are paid to work, while I'm not.

Also, talking about making the phone call, I think for an unknown person, calling them without any beforehand communication is rude. If a friend calls me (which my phone will show his/her name, assuming I have friends), I'm ok with that. We're friends and I'm expecting that. But unknown people? No, thanks. I always text the person and ask if now is a good timing to call him/her before making the call. I hope others can ask before calling me too.
