Received a phone call HR interview several weeks after college career fair. This part took about twenty minutes, and was mostly about talking about past projects or work experience. Then the recruiter schedules a technical review, where the interviewer will ask basic programming questions (choose two languages out of MATLAB, Java, C/C++...) and math questions (calculus, diff equations, linear algebra). The technical interview takes about 45 minutes, covers basics, but you might want to brush up on these topics. No trick questions
