I had my first interview with a lady from the HR, followed by another one with a prospective manager about two weeks later. They were both very generic, run-of-the-mill interviews. The whole process lasted about a month.

The interviewer contacted by email. Due to the location between the interviewer and applicant were in different countries, we were using google meeting for the interviewer process. The first interview was around 20 minutes. Maybe it depends on how you are going well or not during the interview. However, the interviewer was helpful and very friendly.
