How would you answer these common interview questions?

I haven’t had too many interviews in my life. I’m graduating from college soon and I have been applying for jobs. I’m excited to start a new chapter in my life but also nervous. I don’t know what to wear or what to expect! I’ve been googling the common question asked in the interview and here are some that has me stumped. How should I answer this, what would you answer?

Will you make sacrifices for our company?
