OfferUp Data Scientist Intern interview questions

I had two interviews, one with the manager and another with a member of the data science team. Both of these went fine and were pretty typical data science interviews. The recruiter followed up saying congratulations and that they were going to proceed with an offer only to email me back a week later saying they couldn't give me an offer because they don't hire interns remote. I had told them during the interview process I was open to relocating so this caught me off guard. I told her I was open to relocating but then she started giving me excuses saying it was a legal issue and she couldn't even give me an offer letter until I moved to Seattle 2 months later. This was very shady and gave me the impression that she screwed up and was just trying to cover her mistake. I copied the management in on the email chain asking what was going but just got radio silence. I'm guessing in the mean time they gave someone else the offer. Although the actual interview process was fine, overall this was a very negative experience for me.
