Did they use an outside recruiter? In that case the recruiter should know the size, and if they are (as is typical) on commission, are incentivized to suggest to you a number at the high end of the range since their commission will be higher. They are also incentivized to not suggest a number too high for you but sadly most are not that clued in.

Since this is your first full time gig, you can always say so (since they know already from your resume) and simply say "I don't know what's a reasonable wage in this city; I'm excited to work for you and expect to be treated fairly". You can find from glassdoor what other companies in that city are paying -- if they are in the neighborhood of those prices, go for it.

After all if you later find out they are screwing you you can use your experience to go find a better, better paying job. In the mean time you can learn stuff and do good work for them -- once you leave (for whatever reason) you can do so with your head high.
