It's not unsual to layoff 10% of your workforce in hardware companies but it is unusual for a "growing" company. To put in perspective Pratt and Whitney laid off about 10-15% a couple years ago when they were in between the phasing out of the old engine and ramping up the new engine. Sometimes companies are unlucky because there is a drought where the demand for the new stuff is lower than the demand of old stuff but you have to phase it out to maintain product lifecycles for sustainable growth.
