Ventajas
Matrix is a great place to work - great people, fun activities (half day for a private movie theater showing, raffles, contests, free lunches, etc), great benefits (gym reimbursement and a 4% 401k match) , awesome job security, fantastic growth potential (I started as an examiner less than 10 years ago), great work-life balance (I have never worked nights, weekends, or holidays in any of my many roles here), and management teams that genuinely care about their employees and do their best to empower the front-line employees to decide what our processes look like.
Desventajas
None as far as I'm concerned - we do our best to gather feedback from our employees and apply it to make our offices better work environments with each passing day. No job is ever perfect, but we can always be better at everything we do & having an employer that is always considering ways to improve the experience of their employees is an awesome thing. Remember that even the companies that are ranked annually in the "top 10 places to work" still have negative reviews from disgruntled former employees on this and other review sites - take them with a grain of salt! There's a reason the average examiner tenure in NY is over 7 years.
