    I worked at AppNexus full-time (More than a year)


    Benefits are very generous.
    Work culture values good working relationships and team-building.
    Guiding beliefs and values are fundamentally intended to make the internet a better place.


    Some knowledge silos due to company size.
    Very explicit, separate teams which might work on the same projects otherwise.
    Free snacks (self-restraint).

    Anonymous Interview Candidate in New York, NY
    Declined Offer
    Positive Experience
    Average Interview


    I applied online. The process took 3 weeks. I interviewed at AppNexus (New York, NY).


    I applied online, 1 phone screen, then 1 day of final round (1 hour interviews each, 4 total interviews with 1 hour lunch in between). You get the offer or get rejected in 2-3 business days. Everyone is very nice and helpful.

    Interview Questions

    • 1) Name a time when you (insert all scenarios), all of the standard things you might prepare for normally
      2) Analytical test, what is AppNexus' total revenue, how many total bids does it serve, and in what specific markets
      3) Describe a concept and explain it to me like I was a 5 year old
      4) Name a process that you could improve (ex. public transportation system of Manhattan, unemployment services) if you had a reasonable/working budget
