Olo Full Stack Software Engineer interview questions

I applied online and received an email with a link for a coding exercise to complete regarding parsing JSON data. The coding exercise seemed appropriate for the position. I completed the coding exercise within the specified time (3 business dayw) and posted it per the instructions. I never heard back. After 2 weeks I sent a follow-up email to Olo and again never heard back. This seems very unprofessional to me and makes me wonder if Olo has the same disregard for employees as it does for applicants.
