The MCCA is an interesting environment comprised of 2 large convention centers in the heart of Boston. The network is top of the line and technology is very well supported financially. The engineer-level employees are incredibly competent and hard working. Management, on the other hand, is often dismissive of employee concerns, intimidating when under pressure, and unsupportive of any form of work/life balance.
I would recommend this company as a place to grow your resume, but do not plan on making a career here.
