How I personally feel about ETS-Lindgren would not be printable, but what I professionally did was make a lot of money for a company that didn't deserve it.
Working for the Owner/President was a delight.
Assignments, by subsequent inadequate supervisors, proved to be some of the worst experiences of my career (see Cons below).
Note: ETS-Lindgren, before 2004, was called Lindgren RF Enclosures, when it was by far a superior company to work for.
Lot of free meal/meetings, manufacturing on premises, Independently researched and developed products that lead to Patent Awards.
Director of Engineering couldn't design his way out of a paper bag, stole designs from other engineers and took credit for them.
