Real, anonymous reports from people who interviewed for Software Engineer at Deutsche Telekom, newest first and distilled into what to expect across the loop.
My first round was short and almost breezy. It lasted about 30 minutes and started with me introducing myself, then they walked me through what work they did there and what equipment they used. The only technical thing that really stood out was how they asked about my experience with lab equipment. Overall, it felt straightforward and not stressful, more like an early fit check than a deep technical assessment.
One hiring path I experienced felt professional during the actual conversation, but the process soured right after. After speaking with a team under the broader Deutsche Telekom group, I got post-interview feedback that didn’t match what I had already discussed. The feedback pointed to ServiceNow and “large organization” experience as reasons not to move forward, even though ServiceNow never came up during the job discussion and I had already said I’d used it before. I also mentioned prior work at a big multinational tech company, so the rationale didn’t feel aligned.
The interview process typically consists of multiple rounds, often starting with an HR conversation, followed by technical interviews that may include coding challenges and project discussions. Candidates can expect a mix of foundational topics and deeper dives into their past work, generally structured to assess both technical skills and cultural fit.
Candidates should prepare for a strong emphasis on core technical concepts, including data structures, algorithms, and specific programming languages like Java and C#. Expect questions that assess both theoretical knowledge and practical application, often with follow-ups to clarify understanding.
While some candidates experienced clear and timely communication throughout the process, others reported significant delays and vague feedback post-interview, which can lead to frustration and uncertainty about their performance. It's advisable to seek clarity on expectations and follow up if communication lapses occur.
The overall atmosphere during interviews is generally described as professional and supportive, though some candidates encountered negative experiences with interviewers who appeared disengaged or overly strict. Candidates should be prepared for varying dynamics and maintain a positive approach regardless of the interview tone.
Candidates noted that the scheduling and logistics of the interview process were often well-organized, with clear communication regarding interview times and follow-ups. This aspect can significantly enhance the overall experience, making it feel more manageable and respectful of candidates' time.
Candidates reported mixed outcomes, with some not receiving offers despite feeling the interviews were fair and structured. Reflecting on the experience, many emphasized the importance of preparation and understanding the company's culture, as well as the need for clear communication throughout the process.
