    How diversity in science can benefit communities

    I am a scientist at Illumina, and I get to do amazing things. Last year, I was on a team that produced the first Atlantic bottlenose dolphin DNA sequence, findings that could support conservation. I love my work, but getting here wasn't easy, and I couldn't have done it alone.

    I have been working at Illumina full-time (More than 3 years)


    This is a very fast moving company constantly innovating and changing. I know many companies say this in their values, but here you'll feel it every day. No two years are the same, no two months are the same. Everyone is collaborating towards the same end vision; to unlock the power of the genome, to transform healthcare and beyond. It's dynamic and very meaningful. I find it very motivating to know the work we're doing is improving thousands of lives today, and millions in the future!


    The Pros can also be Cons if it's not a good fit culturally. Someone who needs a regular routine or struggles with the undefined would not align well at Illumina. Because the company is pushing the limits of what's possible, and doing things no one in history has done, there is a lot of undefined gray areas. This can be a pro if one likes charting their own course. If an employee is looking for a more defined and routine culture, this is not a good fit.

    Advice to Management

    Continue the improvement on prioritization. There can't be many number 1 priorities. Forced ranking could be a useful tool to hash out relative priorities. Great trend here already, but still more to do.

    Average Interview


    I applied online. The process took 2 weeks. I interviewed at Illumina (San Diego, CA) in April 2016.


    A phone screen was arranged the day after I applied. Two onsite interviews scheduled straight away. They were one week apart. An offer was made two days following the last interview.
    The Talent Acquisition team was extremely professional, responsive and accommodating. It was a wonderful experience.
