Atos Software Developer interview questions

Just came back from my interview at ATOS Singapore, for the position associate consultant Very straightforward interview, the lady is the project manager itself, also the hiring manager. Ask me question on software and database - what is the step of software development? - what is the advantage of database Normalization? what is the disadvantage of database Normalization - What is the different between different network protocol - what is regression testing? what does it do? - What is the different between waterfall methodology and agile method methodology My least confidence question will the database question, lucky I still remember a bit. Manage to answer on the normalisation. The interviewer is a Malaysian lady, she asked me a lot of technical question, and look quite strict. Some of the part I think I nvr do well. She ask me if I mind take up some govt project, I say it is okay. I also show some passion and interest in the Atos company. When I walk out of the company and go take the MRT, the HR suddenly call me and offer me this position.
