I applied online via LinkedIn for the San Francisco Location. First the HR headquartered in France gave me a questionnaire to fill out, after two weeks I was scheduled for a skype interview. During the skype interview the employer asked some basic background questions and also tests you on some knowledge of the field and metrics. Afterwards an onsite with a senior team member. Everything until this point was rather positive experience. However, after that interview I just never gotten a response back. I sent one email every week for 4 weeks to ask how the process is going but I never received a reply once. This was really unprofessional for an employer that already interviewed a candidate onsite and overall led to the negative experience.
