Negative Experience
Difficult Interview

Application

I applied online. The process took 4 weeks. I interviewed at Illumina (San Diego, CA) in October 2014.

Interview

Applied online -- heard back about 2-4 weeks later for a phone interview. Phone interview lasted 45 minutes and included both behavioral and technical questions. Most questions focused on basic statistics and knowledge of DNA. For example, they asked about what average (mean) was, what standard deviation was, what a student t-test was. Then came the 'explain these to a 5 year old' questions. I was not ready for that. Explaining the concept of a mathematical average to a 5 year old is quite difficult when that question is completely unexpected.

    Difficult Interview

    Application

    I applied online. The process took 3+ months. I interviewed at Illumina (San Diego, CA) in May 2012.

    Interview

    I applied online and heard back after 3 months. I had a phone interview scheduled for the next day. I was told I would be speaking with the HR manager but I actually spoke to the hiring manager. I was asked about my experience, why it was relevant. I was quizzed on basis statistics (explain mean, median, mode, sd, variance, distributions); basic biology (bonds in DNA, basic structure and properties of DNA), troubleshooting (microscopy, applications), windows OS questions, quality assurance questions. The interview was quite difficult. I was not quizzed on anything that was their job profile. I got a call back within a week that they were taking candidates with more industrial experience forward.

    Application

    I applied online. The process took 1 day. I interviewed at Illumina.

    Interview

    Got a call from HR for a phone interview opportunity. Scheduled for about a week later. A Hiring Manager called and asked some questions about previous experiences listed on the resume. Then began asking odd/basic level questions most likely to determine a fundamental understanding of the qualifications listed on resume; these questions were not very indicative of technical ability though and were very obviously picked or prepared from a list by HR.
