4 rounds including extensive written technical exercise. Good communication from the recruiter and generally very nice interviewers. Sometimes unclear when you will hear back about the next stage of the process. In total, process took 3 months

The interview process was fairly straightforward - there was one assignment and two seperate interviews with program staff. There was no HR interview. However, there was a significant time lag - a couple of months - between initial application and hearing back from the organization.
