Smart Columbus interview questions

I read previous glassdoor reviews and wish I would have listened. I had 4 interviews, which is clearly time-consuming. For the fourth, they asked for examples of my work to be emailed and presented, as well as building a strategy to share via email and present. After all of this time and energy spent, not a single person nor the recruiter had the decency to follow up with me despite my multiple inquiries. Not even as much as a thank you or an update on my candidacy, it was completely unprofessional. Assuming this reflects their workplace culture philosophy and treatment of employees, I would avoid at all costs... and insist on an NDA signed and/or heavily redact your work before sharing. For being an organization dedicated to the residents of Columbus and priding themselves on "connecting", they seem to have forgotten the basics of how to be human.
