Pros

-Illumina has lots of smart and talented people. -Nice gym and facilities. -Decent benefits (salary, 401k, health, etc.) -Good "brand" name recognition on CV -Industry leader in whole genome sequencing and a strong array business

Cons

Illumina was a great place to work.... for awhile. Unfortunately, their market dominance and arrogance has caused them to expand too rapidly and has left them seriously vulnerable to outside competitors. Internally, the place is in shambles in regards to organization, GIS, and overall direction. Are they clinical or research? Too many chiefs and not enough indians is a general rule of thumb at Illumina. Middle-management is bloated and decision making was painful and slow. Cross communication between groups was very secretive and office politics galore.

Pros

Amazing industry doing good in the world, super smart and friendly people, what else can you ask for?

Cons

None, really. It’s a big company to it takes a bit to get to know process, etc but that’s to be expected.

Pros

Stuck with them for 7 years because it was good back then. Comp is good, benefits are good, and if you're on campus its a nice experience. If you find the right team it can be a dream, but the flipside can be awful. Overall they have a lack of direction in what is turning out to be a highly competitive market.

Cons

Corporate bureaucracy and internal politics are strong but could be worse. The benefits were better in the past and all the perks are winding down with time as they tighten the budgets and try hard to pivot away from dying segments
