Can/should I push back my FB internship interview

Hi guys. So HR just reached out to schedule my first interview but the latest I see on the calendar is end of August. I don’t feel ready at all since I’m still very underprepared and I need a lot more time to practice LC and maybe even finish a few of the projects I’m working on. I’m getting quite anxious and stressed about it because I really don’t want to do the interview in the next few weeks. Is it possible to ask whether I can push it back further? Or should I not do it because I’ll risk pissing them off?

Dude, by the end of August all internships will be done and seniors will be looking for full times too. If you can be ahead of the game don’t push it back just do it. You’ll never feel prepared “enough”
