I applied through an employee referral. I interviewed at Siemens (Atlanta, GA) in Dec 2016
Interview
Long and comprehensive - There were lots of detailed questions about math, computer science, and c++ specifically. It took about 3 hours, but there was lunch included. All the interviewers were very warm, helpful, and smart.
Attended four rounds of interview, two technical, one manager round and a HR round.
In technical rounds questions are from easy to difficult level. Good Experience, I did not get the offer.
Online Technical Test which is basically MCQ based test and then subsequently followed by technical interview by a panel. Technical interview is based on the job that we have applied for and the specific project that the job is posted for.
