Simpplr Implementation Engineer interview questions

Applied and was contacted a few days after to setup an initial interview. Interview was scheduled. Interview was conducted and I was told that I would hear back on whether I made it to the next round or not. Waited weeks and heard nothing. Sent an email to follow up on the status of my candidacy. According to the Read Receipt my email was read, and seemingly ignored, as that was over to weeks ago. Very unprofessional, and a waist of my time and energy.
