I found a job I am interested in and I have some deal-breaker questions I want to ask before applying (example: if they offer relocation, remote work, visas). I tried to find the answers on their site/internet without success.
My goal is to save time (to both parties), considering this company has a policy of only notifying shortlisted candidates.
Because the job listing doesn't have a person responsible, I contacted one of the HRs of the company, Jane, via LinkedIn. I told her about my interest in the position and if she could point me to the person responsible as I had some questions before applying.
On the same day, Jane came back to me saying that Joe is the one responsible but she'd be happy to answer my questions.
My gut tells me I should ask the important questions to Joe, considering they may be an opener to create a connection that could help me land the position, but Joe may not be as responsive/eager as Jane before even applying.
I though about asking Jane one of the questions and send the others to Joe to have a fallback in case Joe doesn't answer.
What's the proper etiquette for handling this situation?
In case it is relevant: Joe and Jane have the same role and seniority stated in their LinkedIn.
Update: I followed the accepted answer's advice, but now I've been waiting 3 working days for Jane's answer, see the follow-up.
