T-Mobile (after merger with Sprint) - Senior Software Engineer T-Mobile Employee Review

Software development at T-Mobile was about four years behind where Sprint was, pre-merger. T-Mobile depended excessively on contractors and third party consulting to do its development, so they couldn't keep their apps current and functional within the rapidly changing tech industy. Too much groupthink in the decision-making processes. Too much reliance on confirmation biased echo chambers, which leads to skirting around real problems with questionable decision-making. More of a marketing company, not as much a software development/engineering environment.
