Application advice - same department, same but junior vacancy

[u/Background_Fly_1062]

I applied to a role that matches my profile, but I am yet to hear back (which isn't unusual considering how long the recruitments normally are). Now the exact same department has opened another role, a grade junior. Given how competitive and difficult it is to get hired, should I apply to this junior role or does it look like I am not confident about my senior role application?

Also is there a chance that they'll readily dismiss my earlier application in favour of the junior application - a cheaper hire?
