Cantonese interview, only let me introduce myself in english. Then asked few questions about my major and how does it relate with this job. After that, asked me some technical questions.

The HR contacted me very quickly. Interview was with the bosses. They asked technical questions and some case studies about my previous experience. They would review your resume, so everything you said there must be true. They will ask questions about it to make sure you're not lying about your experience.
