I was interviewed over the phone both by local HR recruiter and then by hiring manager. I got accepted after hiring manager interview. Then a couple of days later I was told I have another interview with a line manager. Their interview process is confusing as a general experience.

Several interviews and assessment centre. In depth checking of understanding prof services environment. Good explanation of the issues of the organisation and requirements of the job. Follow up to check interest and pursued until issues addressed and satisfied with offer. Lengthy negotiations.
