I was contacted by the White Clarke recruiter directly.
First there were 2 tests to assess my suitability for the role (PI behavioural and PI cognitive). Once I had passed those tests, interviews were set up.
I had 2 interviews, with different stakeholders.
After the interviews it took about 2 or 3 weeks before I got the results back on whether I was successful or not.
Overall from first contact to offer took about 6 weeks.
