    Average Interview


    I applied through an employee referral. I interviewed at Illumina.


    I had a video interview first where you answer a few pre-determined questions. Then I moved to phone call with the hiring manager. Then I was followed with an onsite interview where I did a presentation and had individual interviews with a bunch of people.
