Syntellis Performance Solutions SE Interview interview questions

Overall straight forward interview process; moved through the first 3 interviews quite quickly. The initial call was with the recruiter, the second was an interview with the hiring manager, and the third was an interview with the hiring manager plus their manager. Lastly was a presentation demo, which is pretty antiquated in my opinion but nonetheless, I understand the desire to see the skillset. I was supposed to hear back at the end of the week (the presentation interview was on a Monday) and was essentially ghosted. I reached out to the recruiter and sent a follow-up email to all I spoke with but no response or feedback. If you're making it through the entire interview process I believe you should be receiving some sort of feedback, regardless of the outcome. I also saw that they had recently reposted the job listing to Linkedin as well.
