I applied online. I interviewed at Illumina (San Diego, CA) in Apr 2017
Interview
Digital Interview, it had 6 questions and 3 of them were asking about your past experiences while the other 3 were technical theory. It was fun to do but I did not expect those type of theory questions and they were worded strangely so I didn't quite understand what they wanted.
It starts with HR review, then a video interview. The video interview will start with questions about the resume. Then, they asked a question from Leetcode via Leetcode. It was a two-sum problem.
Interview questions [1]
Question 1
Solve a 2-sum problem. It is the typical 2-sum problem directly from Leetcode.
Easy process, very simple phone screen followed by a algo / data structures technical round. I would say to just focus on getting better at leetcode, and to not sweat it too much.
focus on technical, no much behavior question. need to match job description, whole day interview with 5/6 interview panel. lunch provided, and onsite interview. remote allowed but prefer to be onsite
