Starbucks Part time job application

Hiii, I am a 3rd yr student and i really wanted to apply as barista at starbucks (part time) just wanted to utilize my free time while studying. There is open house hiring in malabon, and i'm too nervous to go, any tips y'all

Super lala ng anxiety ko and i think I can't do it alone, may nakakaalam ba sa inyo ano ginagawa in open house hirings and ano yung mga step? Nakakakaba po ba ng sobra?

Also sa valid id, will they accept soft copy of national id, or kahit i-print ko lang, i haven't received the physical copy of national id kasie. Or kahit school id na lang?

Lastly, do they really call and ask those u put as ref on resume?
