Guys pls advise Or Guide for my interview.

Guys I am working as a QA in TCS and mainly as a manual QA, And learned automation by my own But not that pro in automation, The thing is tomorrow i have a f2f interview in Cognizant and Ey as Automation Engineer, bcs have an experience of 4.8 now in tcs for now.

I am in confusion now whether I need to attend tomorrow's interview or not, because I haven't learned anything so far because of my work and didn't expect they will mail for an interview call also since this is my first f2f and this evening only I got the call letter.

And one more doubt Will I be able to attend the other interviews for cognizant or ey once If I fail in this. current interview..?

Pls guide me guys

What I will doo...?
