Process is simple. First, call with the recruiter. He setup a call with hiring manager. Later they gave take-home case study. But don't expect a quick response, for each interview and response I waited min 2 weeks. On take-home case study they asked to record a video and after 2 weeks they rejected saying communication issues. If my communication isn't at an expectable level then why haven't caught it in the first interview with the hiring manager? I felt I wasted my time working on a case study for a week.
