1 half hour telephone interview. The interviewer did not put much care into asking questions. You could tell it was all scripted--making for the stereotypical scripted answers.

Four rounds of interviews. The first is an interview with the hiring manager. The second is a technical exercise where they tell you that they give you a week to solve it (but then they give you two days). A third one with questions about the exercise. The fourth would be an interview with a SE, which is sometimes merged with the third interview. No feedback received from them after a month. Plus, they forgot to attend a call they proposed but never replied to the confirmation email
