Went through skype interview and in-person interview with the Recruiting HR as well as the manager of the team. It was an engaging conversation, even though I did not get an offer, it was a great interview experiences.

Drop a resume online with a cover letter and one interview in-person. Super casual, more focused on long-term growth and returning to T-Mobile. They like ambition and initiative people and want to help you grow. My interviewer was very nice
