After your resume passed through the filters and got the attention it deserves, you will receive an email to plan a phone interview with the recruiter that last no more than 20 min. This interview is done through Skype and is quite informal, just to get an idea of who you are and what you want.
The second step was a phone interview with the program manager, which is based in San Francisco. There you will be asked to talk about your professional experiences in an informal manner.
The last step is an assignment to do at home.
