Ochre Bio interview questions

Applied for a scientist position at the company. I am based in London but was open to relocating to Oxford for the job. Was contacted by the hiring manager about the position asking for details to schedule a time to call and chat. They then asked about my location and I repeated that I am willing to relocate for the job. They then completely ignored me even though I chased them multiple times but they didn't reply. Very unprofessional and bad experience.
