Internship Interview

Got three calls from my internship coordinator today. After shifting here and there, the companies that I applied for just said that they will get back to me and apparently that didn't even happen at all, despite I was so desperate to just confirm and get over this as quickly as I could. My internship is going to start next week and I still haven't got accepted in any company yet. 

My coordinator told me to attend an interview next Tuesday at 3.00pm, even though that wasn't the company I applied for. I just want to get over and done with it.


Please.
