Entrevista
I applied online and got an email from recruiter few days later. Scheduled a phone interview afterwards. The interviewer first introduces his team and then go on asking me statistical questions. I didn't know the answer and struggle for a while. Then he moves on to ask me to explain the algorithms I used before. The phone interview was 45 minutes.

30 minute phone screen with HR, followed by an interview with the hiring manager. HR would not even provide a salary range for the role, which was very weird. The HR rep was not familiar with the role and seemed to be reading from the JD when I asked questions about it.
