It's not an outrageous working week, but it's not normal either. Right now I do bang on 9-5, I've done 50 hour weeks in the past but because it suited me and there was recompense but I wouldn't have liked to be told it's "normal"- it was me being ace.
Suppose it's about context...
If they're trying to convince you there's nothing unusual about it and that everyone does it, that's probably bad- frankly to me it might be a "walk away" sign because if your relationship starts on that basis, it's not likely to go anywhere good.
If they just mean it's normal for the company, or something of that ilk, that's perfectly innocent and fine.
And equally, it might be that they genuinely think everyone does it- it seems to be almost universal that whenever people work ungodly hours or unpaid overtime or any other undesirable working condition, they convince themselves that "everyone does it". The woman in my office who did loads of unpaid extra time insisted "everyone does it" even though everyone else in the office worked at most 30 minutes a day and claimed every last button back.
