    Average Interview

    Application

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

    Interview

    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.

    Application

    The process took 6+ weeks. I interviewed at Illumina.

    Interview

    Rude and unprofessional interviewers, seemed dismissive and not interested in really getting to know me. It also took nearly 2 months to be reimbursed for expenses. Overall, it left a poor impression of the potential work environment and I would not recommend pursuing a role here.

    Average Interview

    Application

    I applied online. The process took 4+ weeks. I interviewed at Illumina (San Diego, CA (US)) in April 2018.

    Interview

    Applied, got an email 2 weeks later asking for a type of phone screen interview. I say 'type of' because it wasn't through the phone, but rather you record yourself answering questions that are predetermined. I didn't think it was as accurate a measure of an applicant as you get through a phone interview, because my answers felt rushed and awkward.

    It took one month before someone finally emailed me with a rejection letter. It would have been nice if there had been more transparency as to what they were doing all of that time before the rejection. The hiring manager never replied to my communications after that as well. Overall, more communication between HR/hiring manager and the applicant would have been nicer and would have felt more respectful to the candidate.

    Average Interview

    Application

    I applied through an employee referral. The process took 4 weeks. I interviewed at Illumina (San Diego, CA (US)) in November 2018.

    Interview

    Step 1: completed the recorded video interview with the standard 9 questions. Only 15 minutes of answer time, however, the time to practice, get the setting correct and with the prep time for each question, the actual interview time was closer to 45 minutes.
    Step 2: phone interview, set up three weeks out, for 30 minutes, actual was 60 minutes. No followup ever.

    The process took 3 weeks. I interviewed at Illumina.

    Interview

    The most backward low rent recruiting team I’ve ever encountered. They are poor at interviews, poor at following up and great at ghosting candidates. If this is how Illumina shows it’s stuff to candidates, then I can’t imagine what kind of horror show is going on inside the company. I won’t be wasting my time ever again with this unprofessional bunch.

    Average Interview

    Application

    I applied online. The process took 1+ week. I interviewed at Illumina (San Diego, CA (US)).

    Interview

    Spoke with hiring manager and a mutual fit was apparent. Followed up with HR who was rudely short in temper and got aggravated when asked questions about the role and structure of the team, package details, etc. Felt as if it was my privilege just to be speaking to Illumina HR. Needless to say, this ended shortly after the HR call. My advise is to proceed with caution HR and focus on hiring manager/team. Good luck

    Interview

    There were two phone interviews, both with mostly good technical questions, can not disclose
    They were pretty standard for the position - algorithms, data structures, complexity, several specific algorithm for the data processing
    Also they were not advanced to the face-to-face interview I feel that I would be very good for the position

    Easy Interview

    Application

    I applied online. I interviewed at Illumina (San Diego, CA (US)).

    Interview

    Was sent a form from a recruiter to fill out asking about salary, location, how I found Illumina, general questions. About a week later, I got an email back saying they would like to move forward with me to a phone screen. I had about a 45 minute conversation with two senior software engineers, covering a bit about my background and usual java questions. I was then invited for an on-site. The on-site consisted of 3 (maybe 4, can't quite remember) panel interviews and a coding challenge where I wrote some code with half completed projects. I had about an hour to write about 5 programming questions without use of the internet. Everyone I met was extremely nice and had a pleasant experience.

    Interview Questions

    • Nothing out of the ordinary. Pretty standard Java questions alongside the coding challenge   1 Answer

    I applied online. I interviewed at Illumina in July 2016.

    Interview

    Had a phone screen with two Illumina employees. Went well for a while, but there were a few questions I did not expect which I stumbled on. Nevertheless, in general it was still a positive interview experience, and it gave me some insight on subject I still need to improve on.
