T-Mobile interview questions

I got this chance to interview through a referral. Recruiter reached out and explained the interview process includes 2 rounds One panel round and one with manager. Recruiter mentioned there won't be white boarding and general experience based questions. It wasn't clear what to expect. Interview: It was with 3 principal engineers. They started asking very generic decision based on questions on language and frameworks. Then to deep dive about personal experiences. Questions are too vague that you won't know how to scope your answer, Also they don't help you when to stop. Not even a cross question like why you took that decision instead of other way SMH! they just stare at you. At the middle of the interview I realized its just another ghost job or they interviewing it for another GC position to reject everyone. One of the member left the interview in middle without notice which was unprofessional behavior. After the interview, I even thought about this may be they want to learn about how other company's architecture for their choices. Anyway after couple of follow-ups I got rejection email. It could've been good rejection if they tested my abilities and adaptability and I failed, Instead of a knowledge test anyone can google and learn in 30 minutes.

phone screen, then in person with a supervisor and a few placement type tests to make sure you can type and talk at the same time. pretty standard stuff and everyone was super nice throughout the entire process.
