I was contacted by Texas Instrumets via a Software outsourcing company in México. The outsourcing company reviewed my resume and tested my english skills. Then an engineer of the outsourcing company made some questions about my Linux and programming backgrounds. After that initial screening I was interviewed by the team in Dallas. The questions were regarding how would I start if no documentation was available and nobody knew how they would implement it. So I gave my answer and they were pleased with it.

They conducted 2 technical rounds in person. Each round was taken by 1 interviewer who is expert in the field. Questions check the depth of knowledge of candidate and clarity of approach when solving problems.
