NDA/non-compete disclosure with new employer

I'm pretty naive and new to all of this legal stuff and it seems like I'm learning the hard way about all of it. I signed a confidentiality/non-compete/non-solicitation at a previous employer, and was recently offered an internship (not done school yet) at a big tech company. I disclosed those previous agreements to them and they seemed pretty sketched out about it. They wanted copies of said agreements and to know generally what I did at previous employer. Is this standard procedure for big companies? Is there any chance that this could ruin my job offer? The two jobs are totally unrelated. I just want to make sure that these previous agreements aren't going to mess up my opportunity in anyway, as it is super important.
