Found (UK) interview questions

I had a video interview with two SEO account directors. They asked me the usual things like my career to date, specific SEO experience and projects, what sort of clients I had worked with. I gave lots of examples, with over 10 years experience. They were friendly in the call and the interview took the full time. They very much hinted there would be a second interview for me, but instead I was ghosted. I recieved no feedback and it was a waste of my time during a time I could have been looking for other jobs instead of preparing for them. I don't expect you to reply to every applicant, but I do at least expect even a rejection email for someone who has interviewed.

Applied online. Received an email next day inviting me for a phone interview. They specified a day, not a time and called me. Interviewer asked me only 2 questions and lasted for 4 minutes. I received an email next day telling me I was not successful. Absolute waste of time of my time. The interviewer didn't even bother asking me about my relevant experiences that I had to ask her at the end if she's interested in knowing my academic, professional background and relevant skills.
