Deutsche Telekom interview questions

After an initial CV screening by general HR I've been invited to an online assessment. The assessment encompassed several analytical questions and a motivational self-introduction section. The last step was a 60-90min Interview with two consultants, including a short presentation in english and several brainteasers/case studies.

They asked about my previous experience and related achievements relative to devops role. Negative outlook though. They never sent feedback. Demonstrated a very bad culture. They seem not to respect engineers and others' time.
