Siemens Developer interview questions

Online test and onert 2 rounds It was hacker earth test 15 objective type questions and other one is programming test. objective type are basic questions related c# and oop concept

Interview was good with good technical questions relevant to my experience, attended two rounds of interview, received mail from hr that I am selected, but she assured me offer letter will be released same day, but to my surprise position is withdrawn after 2 months of waiting, don't play with resources, my request to others don't share your professional reference details, they will conduct interviews just for fun not to recruit. Siemens is big cheater in the market
