I received an email from HR and was given a date and time to show up for an interview - nothing else. I found out after waiting for awhile that the HR person was out and I'd be interviewing with someone else in a bit instead but was only given a first name, so I assumed it was another HR person who was filling in. It took me until 10-15 min in to the interview to realize that I was speaking with the hiring manager. The hiring manager seemed really awesome. It really seems like a job I'd be well suited for, somewhere I'd love to work, and a manager that I'd have gotten along with really well. The individual even escorted me all the way to the parking garage, making small talk as we went. I was promised that I'd hear back in a specific amount of time. I don't expect to get an offer at this time, as a significant amount of time has passed with no communication. Overall I was disappointed that I did not get to talk with HR either over the phone or in person before meeting the hiring manager. I felt that I went into the interview with the hiring manager pretty blind.
