    Data Scientist Interview

    Anonymous Interview Candidate in San Mateo, CA
    No Offer
    Negative Experience
    Average Interview

    Application

    The process took 2+ months. I interviewed at Greenplum (San Mateo, CA) in May 2012.

    Interview

    I applied through the company's website. The recruiter got back to me a week later and had a screening phone interview with me. I then had an hour long phone interview with a data scientist on the team. A few weeks later I was sent an exercise/skill test to complete in 24 hours. They invited me for an on-site interview a week later in San Mateo. It consisted of four 1-1s and a presentation. The recruiter got back to me three weeks after the on-site interview.

    Pros: -Data Scientists on the team are very knowledgable and nice.
    -I learned a lot from the interviews. They gave me a lot of insights.
    -They work on exciting projects.
    -Nice cafeteria

    Cons: -The company had poor management and organization skills.
    -The person who interviewed me was changed at the last minute.
    -The recruiter accidentally sent me a rejection email.
    -The hiring manager I was scheduled to talk to was in a meeting and I didn't end up talking to her.
    -The room that I was supposed to give a presentation was occupied.
    -I had lunch with the employees and it seemed like there was a lot of politics/awkwardness between departments.
    -No responses or updates for three weeks despite my follow-up emails.

    Pretty annoying given that the recruiting manager was so far removed from reality.

    Easy Interview

    Application

    I applied online. The process took 1 day. I interviewed at Greenplum in March 2012.

    Interview

    The HR took over a week to setup behavioral interview. Behavioral interview was done by a project manager to gauge my interest in Natural Language Processing.
    After the interview I was told I will have a technical interview. I was even told the interviewer's name, but I didn't hear from the company since. It was really unprofessional of them.

    Interview

    About a week after I applied online, the HR phone interviewed me. It last about half an hour. Questions focus on behavior and also asked how proficient in SAS, R, SQL and Hadoop.

    Then the next day HR emailed me to set up another phone interview with a senior data scientist in the team. She asked a few statistics and modeling questions and let me describe one of my projects in the resume. All are average questions but I did not answer well since I'm not prepared. No response after that.
