Applied online when the position was posted and received word back for a video screen a couple of weeks later. Geared up for a second video screen a week or two after the first, and then took an invite to final round on-site in-person interviews a couple of weeks after that. Cycled through 6 45min interviews back-to-back (with an hour-long lunch break in the middle), each with a different PDRP graduate/leader. Good mix of behavioral and technical questions about how I handle different classes of situations and scenarios, as well as my knowledge and understanding of scientific (and more specifically and importantly biologic) tools and skills, such as cell culture preparation, protein production and purification, comprising my experience. The day concluded with an hour-long tour of the pilot plant.
