Siemens Digital Industries Software interview questions

It was a comfortable conversation. It was just 30min, intros were kept extremely short and we went straight into technical questions. I followed up by email a week after, but I didn't receive a rejection until 6 weeks later, which unfortunately was a very generic email with no personalised feedback

Was ghosted after successfully doing both dsa questions in OA. The questions were of medium level. I tried contacting the company many times. There was no response. So i would say it was a waste of my time
