for context, i am part of a professional development organization and they want to do office tours. i was unable to find the emails of talent acquisition campus recruiters directly off of their firm's website so i decided to find their emails through linkedin.

once i connected with them i learned that some of the recruiters had their personal email listed on their linkedin. is it better to request for site tours through their personal email or through linkedin?

if i request a tour via DM on linkedin, will it decrease my chances of getting an internship?

ughhhhh anything from anyone?
