Scam calls, scam calls, and scam calls

I put in 6 applications yesterday and the today my phone blew up with calls. I was excited at first but then I realized that 90% were scam calls. Welcome to adulthood for me! what’s the best way to Verify a number, ignore these things, and if they didn’t leave a voicemail can I just assume their scam?

(Ps lucky for me I have 2 job interviews now :3)
