Tenable interview questions

After they approached me on Linkedin - I had a 30 minutes phone call with a recruiter that asked very specific questions like once in how much time we rollout a new version in my company. At the end she said they already have people in advanced stages, and after a while I got an email that they won't continue

Very long an unclear, in the end there was no feedback of how it went, it was never clear how many steps tehre would be. It was deceiving, everytime just waiting for the next step with uncertainty
