I applied online, and got contacted by email for an interview. There was one interview that was pretty much entirely technical. Very relaxed setting though, just gauges skills and experience.
Fiz uma entrevista na empresa Physical Sciences (Andover, MA).
Entrevista
It was a very straightforward process, and everyone was really friendly. They reached out to me and scheduled an interview with a few engineers and scientists on similar projects. Discussed the projects I may work on at the end.
