    Average Interview


    I applied online. The process took 3 weeks. I interviewed at Illumina (La Jolla, CA).


    I received an automated response regarding my application within a week. I received a request to do the digital interview which I promptly returned. The in house recruiter shortly reached out to me to set up a follow up phone meeting wherein I was further screened for experience and compensation. She said she would get back to me but never did. Note: She also was late in the call and hurriedly finished it at the half hour mark.
