Very intense back to back line of questioning, Dug deep into personal work projects and how they could have been improved. Would be difficult if you aren't used to someone questioning you quickly for over 30 mins multiple times. Needed technical experience with electronics, which i did not have.

It was a 30 minute phone call with recruiter then manager then senior manager. You were asked about your work experience and then had to go into detail on specifics from your resume.
