    Accepted Offer
    Positive Experience
    Average Interview

    Application

    I applied online. I interviewed at A9.com (Palo Alto, CA) in May 2017.

    Interview

    The interview process is as follows:
    1) Recruiter contact
    2) Technical screen
    3) Panel interview - (4 to 5 engineers)

    The questions in the technical interviews gradually becomes more difficult and they are related to the previous question that was asked from you. Any interviewee will have no problem answering if they really know what is being asked of them.

    Senior Analyst Interview

    Negative Experience
    Difficult Interview

    Application

    I applied online. The process took 4+ weeks. I interviewed at A9.com (Palo Alto, CA) in January 2017.

    Interview

    Two phone interviews including some technical assessment, then on site for 5-6 hours. The whole process is unpleasant, both phone interviews started much later than scheduled time, last minute cancellation, one day advance notice of on site interview....Don't feel being respected, not enough and proper communication from HR uncles I asked. On site was okay however only 10 min for questions and a lot of technical assessment again although they have done two rounds of technical interview.

    Difficult Interview

    Application

    I applied online. The process took 2 weeks. I interviewed at A9.com in January 2017.

    Interview

    Two calls. One from a Sr. Manager and one from the direct manager. HR is very unorganized. I've interviewed with them before and thought they changed. Sadly, they have not. The job posting on their site did not reflect what the actual job requirements were. They seem to bump up the requirements as the process goes on. It's a waste of everyone's time to do this.

    Interview Questions

    • Questions were way more technical than the job posting indicated. Why ask about scripting when the job has nothing to do with it?   Answer Question

    I applied through an employee referral. The process took 3 weeks. I interviewed at A9.com (New York, NY).

    Interview

    Usual process. The whole process took a couple of weeks, from first email to set a time for phone screening, and doing the screening. In comparison with other companies, the recruiter was slow in responding emails and scheduling.

    Scheduled an interview with the recruiter after applying online. Standard phone interview and coded on a white-board like text editor.

Overall a great interview experience.
