1 round of technical interview over the phone followed by a face to face technical round in the local Atlanta office. The last round is one with hiring manager. Except for one Architect in the Seattle office, rest of the folks are all unprofessional and have no clue what to ask in a technical round. The so called Architect of the team here in Atlanta office has been in Sales/Consulting his previous life, and it is surprising to see a company like T-mobile promote non-technical people into those roles.
