      Senior IOS Developer Interview

      Mar 20, 2025
      Anonymous interview candidate
      Athens, Athens, Attica
      No offer
      Negative experience
      Easy interview

      Application

      I applied online. The process took 1 week. I interviewed at Deutsche Telekom (Athens, Athens, Attica) in Mar 2025

      Interview

      I interviewed for an iOS Developer role at T-DIGITAL by Deutsche Telekom. My initial experience with the HR team was fantastic—everything was well-organized, professional, and engaging. However, I found the technical interview a bit unexpected. I was prepared to delve into my projects utilizing reactive functional programming and SwiftUI, a topic I'm passionate about, but the interview deviated significantly and it became a monologue from my side, with only two off-topic questions posed by the interviewers, failing to engage with my CV or introduction. Unfortunately, the interviewers seemed particularly focused on approaches designed to optimize Apple’s legacy codebase rather than modern patterns aligned with Apple’s latest recommendations. Given my age, which is over 50, and noting that the company website highlights an average employee age of 33, I hope this focus on legacy systems and the overall disconnect in the interview were not influenced by age-related biases.
