I hope the story this came from had the guild actually provides some listings w/ pro & cons (tier rating, etc) if asked or something, and the MC is just an (lucky) idiot who input something immediately instead of asking more questions, but the manga really doesn't make that scene seem like she was getting ready to provide a whole info dump.
What happens if it went like this instead: "'Pope'" "...oh. that's too bad. 'Pope' sucks here, 'priest', 'cleric', 'druid', 'bishop' or even 'friar' would've been good to great similar jobs. That's a shame... hope you survive!"
I can see trying not to influence a Seeker to see if they come up with a new job that turns out to be good, but some back and forth discussion should absolutely be done, given how much the Seekers are relied on (oh that's a known class, works like this. oh that's new, describe it and I'll try to give you an idea of how it seems like it could translate, want to make sure you feel like it would be a good fit. or: Stumped? here's a listing to give you some ideas. etc etc).
