      Senior Software Engineer Interview

      22 Nov 2025
      Anonymous interview candidate
      Frisco, TX
      No offer
      Negative experience
      Average interview

      Application

      I applied online. The process took 2 weeks. I interviewed at T-Mobile (Frisco, TX) in Sept 2025

      Interview

      Interview: The interview process was straightforward. A couple of round of interviews, first one with 2 of their senior engineers, and second one with a HM. Despite doing well (answered all the questions asked) and hearing some positive feedback during the interview, I did not get pass the first round. One of the interviewer seemed to like me, he agreed with a lot of answer I said and we had a very positive and collaborative interaction. However, the other one ... not so much. He asked vague questions with a fixed answer in his mind, and when I did not say what he was looking for a couple of times, I lost some points on his scoresheet. I did eventually say what he was looking to hear but that apparently did not save me. Also, the interview was very technical until the final question. The second interviewer, who was not pleased throughout the interview, did a total shift from deep technical questions to a behavioral question for which I did not have an exact match for an answer. I think that hit the nail on the coffin. Recruiter: The recruiter was truly incompetent. Their communication was poor throughout the process, especially after my first interview. Did not get even a generic response about the status of my application. Interviewers and Recruiters both could do a better job.

      Interview questions [1]

      Question 1

      This was an Software Engineer AI role, so discussion about AI, data processing pipeline like ETL, resume related questions, and yes, one random behavioral question at the end which caught me offguard.

      Anonymous interview candidate
      Hyderābād
      No offer
      Neutral experience
      Average interview

      Application

      I applied through a staffing agency. I interviewed at T-Mobile (Hyderābād) in Oct 2025

      Interview

      Interviewers focused on the fundamental skills and how the candidate was trying to solve the problem rather than making it Q&A session. If we can provide our solutions with clarity it would be easy to crack.

      Senior Software Engineer Interview

      26 Feb 2025
      Anonymous employee
      Atlanta, GA
      Accepted offer
      Positive experience
      Easy interview

      Application

      I interviewed at T-Mobile (Atlanta, GA)

      Interview

      Technical interview was more question/answer style. No coding tests. This was more of a test center at the time than software development. It was basic intuition and how I could work with others and the depth of technical knowlege of coding, testing and data analytics

      Interview questions [1]

      Question 1

      What was my experience with database interactions when it came to pulling large volumes of test results from database for business intelligence visualization
