Taking time to think about offer - is this a bad look?

Hi everyone,

I recently received a job offer from a large bank. On the offer letter, it mentioned that I have two weeks from the date of the offer letter to decide on the offer. That said, the HR has been a bit pushy and would prefer that I make a decision earlier.

Would it look bad if I took the full two weeks to make a decision regarding the offer as this is an important decision or is this reasonable as that was the timeframe that was technically given to me?

Thanks
