What's it like to work at T-Mobile?

"Great culture"

5 stars 5 stars 5 stars 5 stars 5 stars

Current Senior Technician in Rowlett, TX

Pros

Laid back, easy going, very relaxed and opportunities for advancement and career enhancement if the individual applies him/herself. They INSIST on a healthy work-life balance. And the CEO is entertaining and has done amazing things for the company.

Cons

They really like to promote from within, which is great, if you're "in", but it can be incredibly difficult to get in. Pay can be a little on the low end of the scale, but benefits are great.

Advice to Management

Make sure that everyone on the teams are pulling their share of the weight; policies come out because of the intermittent 'bad apple'
