Hi everyone,

I have an upcoming SDE-1 Backend interview with Deutsche Telekom Digital Labs. I would appreciate it if anyone who has recently interviewed there could share their experience.

Specifically, I would like to know:

What was the interview process like?
What level of LeetCode questions were asked (Easy/Medium/Hard)?
Which topics were emphasized (Arrays, Graphs, DP, Trees, etc.)?
Were there any backend-specific questions on databases, system design, REST APIs, microservices, caching, etc.?
What programming language did you use during the interview?

Any recent interview experiences, question patterns, or preparation tips would be very helpful.

Thanks in advance!
