GE HealthCare Senior Software Developer interview questions

I have given interviews two times. The process is very slow and exhausting. It was somewhat tough and challenging. There are three rounds of technical including online test first and two face to face rounds. But second time i got interviewed for 4 technical face to face rounds and one managerial on the same day. On line test will be of one hour test in which two programs you need to solve. First face to face differ from project to project as sometimes they ask basic language questions to confirm basic knowledge of candidates, or sometimes they just ask about projects and tools and technology u have used. Second round will be taken by architect and team leads it will be based on languages knowledge, algorithms, design and some brain teasers puzzles.
