    I have been working at adMarketplace


    The company has come a long way since it’s inception and has recently made some great changes for the better. We've upgraded a lot that wasn't working. Happy to have pushed through. It’s a good time to come on board.


    Wish we could build out our social media more - have a little more personality and interaction.

    Senior Publisher Development Interview

    Application Details

    I applied through other source – interviewed at adMarketplace in September 2014.

    Interview Details

    Was contacted by a junior HR member of the adMarketplace team. I had a phone interview and was then brought in to interview with the president of the company. He seemed to like me and told me he wanted me to come in to speak with the CEO. I never heard back. I contacted the original HR person who advised me that the president wanted me to put together a business plan. This was already on top of putting together a list of my top 100 publisher contacts and the level of the people I know there. I put together the business plan (my Labor Day weekend) and sent it in. Again, no acknowledgement from HR. I asked if they had received it and I was told yes and that they thought it was great. I followed up over the next few weeks to see next steps and never heard back---ever---from anyone.
