Airship Sales Development Representative SDR interview questions

Pretty long interview process. Involved an initial phone call, then one with the Hiring Manager in the US, then with the SDR Team Lead, and a series of 3 shorter 30 minute interviews with AEs and SDR Managers across the business. It's a bit annoying that I went through such a tedious process to be ghosted. The Hiring Manager talked a lot about how they like to make the interview process a pleasure, and they even sent a survey to fill out after the first round - but that went out the window after the next few rounds. I appreciate that I may not have been the most suitable candidate, but after many hours of prep, and skipping lunch to be available to interview, I would have hoped someone would have the courtesy to at least drop me an email.
