T-Mobile Software Developer interview questions

HR Recruiter, then had interview loop with 4 people. 3 technical, one leetcode, one general programming, system design, and 1 behavioral interview. Overall not a bad experience, but I didn't get an offer and no feedback why.I felt I solved the coding questions well and had decent communication but didn't get an reason why I was rejected

Got a call from a recruiter. There were three rounds of Interviews. Questions were on BST and BFS I could easily solve them and in 3rd round behavioral questions. After all this, I did not get any call from them. They are only wasting your time.
