Darwin Recruitment interview questions

A Recruiter contacted me and said I'd be a match for their ecommerce client based in Berlin. We got on a short call, it went well, she then endorsed me to the hiring manager. After the HM call, I never heard back anymore. The Recruiter was quite adamant in contacting me during the process; even calling me on my mobile, messaging me on Linkedin, when I couldn't reply straight away (I was also in between a lot of appointments). She also checked in with me after the call. Then suddenly she ghosts me after the HM call. At some point she also asked me to enter my details, even the last few digits of my tax ID as this will be used for Ebay identification. Her approach reminds me of a typical London-style of recruitment, which is a totally different approach for people who are based in Berlin/Germany.
