It's not too difficult, they ask the basic interview questions and as long as you show that we are capable and normal they show positive signs. At the time I was applying for the sustainability department and they asked me about the photovoltaic research that Ive done.

Vlot, niet erg complex. Na sollicitatie onmiddellijk aanbod gekregen. 2 rondes; 1 met HR, 1 met hiring manager aanrader, duurde in totaal ongeveer 2 uur, ontvangen in brussel op kantoor

2 rounds , multithreading required extensively,java,hashmap,collections. managerial round- mostly behavioral questions.overall nice and easy.it was online. Siemens is a nice company but lays off when there is no project without even thinking twice. So think before joining.
