The overarching issue for Spirent is that they seem to have only one major competitor, who in some ways they are able to stay above on certain issues, and then on other issues, not so sure. With only one competitor, the impression that I had when I worked here is that there really isn't a great incentive for them to compete at a higher level, and it shows.
The fact that it is a British-owned company speaks volumes for what is wrong here, since the Brits often believe in playing things from the backline, and do not understand the need to be aggressive in their sales and marketing. They simply won't do it. Fine for the UK, but not for the US.
On team and culture issues, the impression that I received was that some of their employees dislike the company (or their jobs) so much, that they may actually be trying to hold the company back. So between the impression of incompetent executive management and those who are situated lower in the organization who are dead weight, it was a real mess of a place to work at, and I cannot recommend working here for anyone who has any worthwhile career aspirations. There are plenty of better places to work in Silicon Valley. Do not waste your time with Spirent. Seriously.
Good location if you live in North San Jose area.
Incompetent executives, lousy culture, lack of competitive spirit.
