Was told that an over-the-phone conversation was a general screening call, then got an email saying that it was an interview and it was on that basis that I wasn't chosen. No other communications and I was completely ghosted.

The interview process is quite intensive as many competitors are in a round. However, the process emphasizes on your past experience and the if you are a perfect match for the position, just share freely and show you as a confident and experienced candidate who is suitable for the job, they will let you pass.
