I got another interview

So I got another call from the same company, but for a different position. Yesterday I went in for an HR Recruiter Supervisor position, today they called me, and said that there was another positon available at the HR department, HR Vendor Manager, and they wanted to meet with me for an interview. I'm so excited....the interview will be tomorrow, once again during my lunch break. I'm a little nervous too, cause I don't know if there will be a problem that I'm participating on 2 recruitment processes with the same company. I don't know about their policies, but I guess they have a database with that kind of information. I just hope that this doesn't cause some kind of misunderstanding about my reasons for applying to both jobs.

Edit: I knew it!! there was a problem, hopefully nothing bad. They just called, wanted to cancel my interview for tomorrow afternoon. They couldn't say why, just that for the moment they would not continue with this recruitment process. I hope this doesn't mean that I'm also not getting the HR recruiter supervisor Position. That would suck!!
