I have been working at L3 Technologies full-time (More than 10 years)
Nice folks; no BS; very little politics; people make and keep long-term working relationships and there is more trust and loyalty between workers than in any other company I've worked. Oh yes. . .onsite gym! However, mileage *will* vary greatly between locations since LLL is comprised of acquired businesses.
In comparison to most companies, there is nearly zero opportunity for upward mobility (with some exceptions of course). The facilities are a wasteland and the office are horrid. But again, the people are great. The health insurance is expensive and doesn't do a lot, but that's not uncommon. The wellness programs are seem to be there just to exists. . .I don't know anyone who's super excited about them.
Advice to Management
Put some money (not even a lot) just some toward improving offices and working environment. It's difficult to concentrate while smelling hex chrome, MPK, and hearing hammering, grinding, and such all day.
I applied through college or university. I interviewed at L3 Technologies.
There were two interview rounds. The first one was at the career fair at my university then the second round again at their office. Mostly behavioral questions and explaining my experiences listed on my resume. The interviewers were very friendly and the contacted me less than a week after with an offer.
