Alot of required overtime hours 50-60 hr weeks, including weekends without direct compensation. Frequent short unplanned trips, not a good family job.
Bonus program can be difficult to obtain and is highly dependent on the market and the engineers marketing ability. Stuffy corporate headquarters, no comradery between employee's.
High Turnover Rate with employees. High Stress, but interesting and rewarding work. Everyday is different.
Can set your own schedule. Flexible management.
