"Great culture"

5 stars 5 stars 5 stars 5 stars 5 stars

Current Senior Technician in Rowlett, TX


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.


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'

"Fun, Exciting, Big Company"

Current Business Analyst in Bellevue, WA


There are many good reasons to work for T-Mobile. Discounted phone bill, discount towards accessories, and good benefits package to name a few. The company is growing and will soon be in the hunt for the top spot in the telecommunication world.


Just like other large corporate environments, its not what you know its who you know in order to advance your career further. Pay is fair could be better.

Advice to Management

Stop managing and be leaders! Listen to your employees, be proactive in identifying issues rather than ignoring them.
