ImmediaDent interview questions

Was contacted by someone I'm assuming in corporate for a phone interview on a Monday. Asked my availability and we ended up scheduling on Wednesday at 530pm. Day of interview at around 6pm no call. Reached out the next day by email and person couldn't seem to figure out how she forgot to call. Rescheduled for the same day at 430pm. No call received at 430pm, around 515pm I get a call from her saying her meeting ran late. After ten minutes into the conversation she informs me that the lead has been taken and she has a front desk patient coordinator position open for less pay. I explained I applied for lead and asked if it had been filled or taken she says yes. How can you have someone fill out a application for one position and interview for something totally different?

Initial phone interview with recruiter, follow up interview with Area Manager. I came back and shadowed the front staff for about an hour. Overall very easy, laid back environment. After the interview, the recruiter reached out to me with the offer.
