Tate & Lyle interview questions

Applied via Linked and was contacted direction by the recruiter. Telephone interview first with Recruitment Manager then Skype Interview with Recruiter/manager. Then 3 interview was face to face in London.

I applied directly and quickly ascertained the role was being managed by a third party recruiter namely cohesion recruitment who are based in Birmingham. This was the worst experience ever. They to a long time to contact me,I had to chase and then had a telephone interview with the agency that was an hour. Then I was told I was one of the better candidates and would be contacted in a week. 6 weeks passed. I had a message from their ATS to say they were conducting interviews still. I called two people at Tate who are recruitment managers and not one message was returned on Linkedin, email or a voicemail. I was recommended to work here by an ex Tate Employee who has moved on to another country. I put other roles on hold for this. Bad process and I am most certainly shocked.
