Got the initial phone call with the recruiter, then moved on to the technical phone screening, but did not get the final interview. The technical phone screening varied from the hiring manager that I was talking to. In one phone call, I was not asked any technical questions and more on my experiences that I described in my resume. On another phone call, I was given a few questions regarding fundamental equations and processes specific to the job description. I would recommend brushing up on the fundamentals (depending on the position) to prepare for the technical phone screening.
