Pros

- Most people are very willing to help and friendly - There are some politics, but not usually there and not as much as I have seen elsewhere, because people in this specific site tend to have worked there for 5+ years within the site - Tend to cut benefits, not people, when market slows down, though, when they do lay people off, it tends to be few and far apart, i.e., people past retirement age, but sometimes also people who did work hard but offended some people in the higher up - (pro or con?) the manager's manager is very sympathetic, though, not being the direct managers, unique challenges faced by females & non-majority people & engineers don't often actually get addressed short-term or long-term, forcing them to leave the company instead

Cons

- (working environment) Over incidents of more than 3 - 4 white male (US or West European) who either currently or in the past work have: shouted at females engineers in the lab (one person did it twice to 2 different females), much more demanding/exploiting of female engineers' time and effort without acknowledgement or compensation, disrespectful or outright abusive behaviors on purpose when addressing of non-white and/or female (e.g., avoid actually using their names, passive aggressively object/undermine them in meetings and in the lab when working together as retribution, etc.) --> some when reported to HR, HR direct the employees to deal with it themselves or report to the manager, but usually it is because the direct manager refused to deal with them so that they went to HR. The only way is to talk to manager's manager, but in most cases no long-term solutions and immediate solutions usually don't change the toxic environment enough for people to want to stay long-term (already 5 female sr & pr level engineers left under these circumstances and toxic environment to females within 4 years) - (working environment) your actual working life depends on the direct manager you have, if you have a good direct manager, your work and personal life would be manageable - (compensation) 2 - 5% annual bonus, not huge, but not nothing, though, in comparison to other companies of the same caliber, it is meager (though, Milpitas location is relatively stable in terms of trying not to lay off people) - Though!!!! I would not discourage female and/or non-majority from applying to R&D, most of the managers and team members are fine, some are even great!

Pros

Depending on the day, the work could be fairly effortless.

Cons

Many times, the work load was unreasonable. The manager of the filter department could be difficult to work alongside at times as he had a bad temper. Coworkers were generally helpful and easygoing. The compensation was not commensurate to the demanding and multifaceted nature of the job. Overall, not a company I would recommend working at.
