    I have been working at Illumina full-time (More than 8 years)


    Smart, dedicated people who live the values of openness, collaboration and moving fast. The executive team values employees and takes tangible actions to continuously improve the facilities, systems and environment.


    Company has historically underinvested in systems and processes, and while Illumina is catching up, it is still somewhat difficult to get things done. Additionally, decision making is not a core competency, with many constituents pulling in different directions and delaying decision making.

    Average Interview


    I applied online. The process took 3+ months. I interviewed at Illumina (San Diego, CA).


    Submitted resume via online application, then got contacted for a phone screen. Heard a few weeks afterward and got invited to onsite at the San Diego campus. The onsite had about 3-4 different stages: group activity, one-on-one with team lead, formal presentation of a model strategy.
