Integrate Sales Development Representative SDR interview questions

Interview processed seem as though it went on for years. They want to vet candidates well which is 100% understandable, however after going through 5 interviews I was completely ghosted and the recruiter completely ignored my email for a follow up one week later. I would have appreciated at least a response stating they decided to go with other candidates, especially considering the fact they are the ones who reached out me first. Not a good look for Integrate to not even take the initiative to follow up when I was told I'd be hearing back the day of or day after my final interview with the sales director.
