Let’s take Nikki as an example again. This time, she’s not looking for a toaster on Amazon. She’s tired of Amazon. She wants to go straight to eHarmony. And then, we have a couple more eHarmony users, such as Jeb, Jon, and Nick.

First we need to consider only those that meet Nikki’s criteria. In this case, that’s only Jeb and John. For us to make a match, Nikki also needs to meet the criteria specified by Jon or Jeb. In this particular case, that’s only Jon. So what are some of the criteria that we are talking about? So this completes the first part of our matching system.

We also have a dedicated team doing extensive research in data science and clinical psychologies to define happy relationships and what personality profiles, what type of personality profiles were most compatible in those relationships

In the second step, we also account for a sophisticated personality traits that a user conveys to us by filling out a long list of questionnaires. Normally, if you meet someone at the bar or at work, a lot of you are, I’m not sure, but, or at a conference like MongoDB World. Hopefully, you’re looking for your soulmate here in addition to Mongo. You probably wouldn’t start by asking them how well did you behave under the stress? That’s not a very good pickup line is it? So with eHarmony, however, we account for all these type of factors behind the scenes seamlessly. Before we accept any user to our matching system, we ask them to complete a long list of questionnaires, about 150 of them, related to their personality, their values, their beliefs, and their attributes. And then, we create a very unique personality profile about you that we’re going to use it later in our matching system. Continue reading →
