Associate Director Interview

Negative experience

Easy interview

Application

I applied online. I interviewed at Illumina in May 2026

Interview

Very bad interview. The senior director was not prepared to the moment, connecting in the cellphone during the moment. I’m not respected during the selective process. The senior director made questions not related with the position, either objective to eliminate me.

I interviewed at Illumina (San Diego, CA)

Multiple levels of interviews (really to many), but great questions and good people. I think I interviewed with 5 total people. The questions were more leaning towards fit then experience they needed.

Application

I applied online. I interviewed at Illumina (San Diego, CA) in Aug 2022

Interview

Unglued. Little to no communication between rounds, really really long process. They act as if they are the only show in town, which for awhile, they could get away with.
