10 challenges is like two weeks of work. You probably studied for 3 to 5 years, and hopefully you'll work there for at least 2 years. Two weeks is not much, even if it is tedious.
Free advice: don't do "homeworks". It's an indication of poorly run and dishonest company, with incompetents at the helm. That's if you get the contract. Most likely you won't (because your are competing with desperate people who lie about their actual effort). Best is to stay out of it.
