Six interviews, five were in person. Was asked for free work, which I detest, but I completed.
In the interview where I reviewed my work, the department head and hiring manager was distracted and spent less than 30 minutes. I had worked on the presentation for 3 hours, as was recommended when getting the assignment.
I followed up three times and never heard back. The courtesy of a generic "we decided to go in another direction," wouldn't have taken them much time or effort. Given the amount of time and effort I contributed, I found this unprofessional and would never recommend them to anyone, for employment or a class. There are other more professional companies out there.
