I had one HR phone interview followed by a technical presentation + three technical interviews. I had close contact with the recruiter, who called me about basically everything, including that I didn't get the job.

A two step process: 1. Phone Call with the recruiter and discussed about the overall company, availability, compensation and my biggest achievement as a mechanical engineer 2. 3 hour long interview with 3 different panelists who were directors and managers. Was also asked to prepare a ppt on my biggest technical achievement All panelists were very kind and enthusiastic and listened to me patiently. Overall a very good learning experience
