["Hi! So recently I applied for this barista job. I've been waiting forever for them to get back to me!", "They haven't called you back yet? I hate when that happens, they make you wait by the phone on pins and needles!", "They just called me back today. I didn't get the job. :( I was trying not to be overconfident. I guess it worked this time lol."]
Don't let it break your confidence though, it just wasn't meant to be. I think you'll land your next application though.
I applied for a barista job recently and wasn't sure I would get the job. I was very nervous waiting for the call.
