Initially the interview process here was seamless and overall pretty pleasant - the recruiter was very professional in organizing the interview, being greeted by the front desk with a beverage (the office is lovely), etc.
I was interviewed by Jordon Rooney. At the time, he was new to the position himself and was looking to revamp the company's marketing. He asked me to complete a "caption" idea for social for a video concept he was working on. He asked for one caption specifically, and I promptly gave him a list of ideas by his deadline. I put effort and thought into my ideas (of course) and I figured he'd have the decency to at least politely decline if I didn't move forward (especially when I put time into completing a project). I emailed him several times with thank you's and asking his thoughts on my work as reminders - nothing.
It is simply common courtesy to send a simple, quick email to someone who put forth effort in dressing up, traveling to, interviewing and completed tasks for an interview process.
