I applied online and received an email inviting me to submit my availability to interview through the link. 5 WDs later, I emailed having not heard back after doing so. I received a call from the recruiter asking on-the-spot questions like why I came to the UK which I found odd. They said they would proceed with an interview and sent me the same email asking to submit my availability. I did so and did not hear back so emailed 2 WDs later. The recruiter told me he was on it at that moment. I did not hear back. What a bizarre and unprofessional experience.
