How my job interview went viral on Product Hunt

0-KRDCtFOAbAz0wq6pRewind back to May 2015. We closed down a B2B retail startup called We had found our “product-market fit”. Unfortunately our startup didn’t end up that successful and we decided to move on.

It was common to have discussions about what was the magic to make great product. We’d fudged our way through and somehow made something people wanted, but couldn’t reach organic growth.

Could I actually create virality?

This is when I took an interview with a Berlin based startup for a junior product management role.

After I passed the HR phone screening, this email arrived:

The case interview required me to recommend improvements to their referral program — a famous growth driver.

My case later transformed into a viral project which generated 40k+ page views.


This is how it all happened.


.   .   .  

Taking a case

At the time, I had no clue what were the best referral programs out there, and most importantly why.

I Googled the topic. The Internet had some good, but scattered resources.

I spent 2 hours gathering a collection of screenshots from 15 different tech companies. The result was messy, but helped me understand some recurring patterns.

Great referral programs patterns I noticed:

  • Fairness. Most people expect fair benefits for both invitee and invited.
  • Alignment. Program rewards are aligned with company values.
  • Accessibility. Referral feature accessibility inside the app is good.
  • Timing. Ask people to refer the product at the right moment is important.
  • Lifetime. Referrals decrease over time when people have less people to share with or less excitement to share. The feature may maximize this instant.

These clear learnings made me craft a 10-slides presentation I later presented on-site.


4 weeks later I had an offer from this great company, and decided to join 🎉


But the story doesn’t stop there…


Validating a problem

At this point I had discovered a problem. Whoever was looking for a neutral, detailed listing of the best B2C referral programs would have to follow the same process. They would lose time, like I did. An amount of time downloading and signing up to all these apps is required.

A few weeks after, I moved to my product position. I learned that building a new referral program was part of my team roadmap and realized that successful referral programs were a black box for many people in the product team.


This moment was the customer validation around the idea.


I knew I wanted to structure my learnings into an educational project. I thought maybe I could get a few hundreds people to read it.


The Mockup

One hour later I emerged with 2 mockups using Balsamiq:

  • A home page.
  • A company referral program flow page.

I’m no designer so there were no graphics, all flat assets and some navigation guidelines.

Prior, I had created a blog where I share executions — like this one — for startups employees. 💎


I decided to build web pages on it.


The traction

I was lucky enough to be reading the amazing book “Traction” which really opened my eyes on the fact that traction and product are of equal importance.

My early thoughts turn into sharing this project on Product Hunt (or PH). A collection of best referral program practices could appeal to the community.

A talk convinced me to get the subdomain A subdomain had less SEO power but added a touch of neutrality toward my blog — which could appeal to PH community.


I started building the pages.


The build

Another 4 hours were spent throwing together the website final version.

I put screenshots, KPIs and tactics notes together using WordPress flexible theme “Enfold” and editing CSS.

Built and deployed in 6 hours. This was the result.

Total 16 pages: 1 Homepage & 15 Specific company pages

5 things I made sure to include on the website:

    1. Top email opt-in bar, a fast way to deploy an email opt-in form across all pages.
    2. Back buttons to navigate easily.
    3. Responsive design to enhance mobile users experience.
    4. Social sharing bar. I created an image that would be displayed when people share the page on social medias. WordPress refers to it as featured image.


  1. Dedicated email address to connect with people.


I sent it for review to some knowledgeable friends and improved it. By the end of day one the “product” was ready.


I needed to launch on PH.


Finding the right hunter

There are plenty of ressources to find influential hunters — like this top 500 hunters list. But finding “famous” hunters means to pitch them first and wait to fit the project into their agenda.

On the other hand less influential hunters have less followers, which mean less people will be notified when your product is posted


A good trade-off was to find a less solicited top tier hunter with a good track record.


I messaged a friend user #560 on PH who accepted to post my project.


Preparing the publication

Prior to launching, I prepared the PH publication:

  • A Title. To find out the most upvoted projects on PH simply press “Space” then “Enter” in the search bar. I noticed most upvoted projects were short — 3 to 5 words — with at least one power word. I went for:

Best Referral Programs

  • A Subtitle. While the title conveys a concise message about your product, the subtitle should convey more clear information, arouse curiosity and push people to click. I used:

A curated directory of startup referral programs

  • A Cover Image. The cover is seen rather small on PH feed so having the fewer words possible is key. I use a gif maker and some complementary flat color range to capture people’s attention.
  • A Few Images. While the cover image is small, other assets will be visible once people are on the product page. I simply added some screenshots and the featured image:
Left: the feature image 🌈 

  • The Comment. I prepared a comment once the product would be posted to tell the community “the why” behind the project. Doing so and mentioning that you are willing to answer people questions will boost the engagement on the project page.


The Launch

The launch was Friday December 9th at 9:00AM — GMT + 0 for 2 reasons:

  • To be there at PH daily counter start and get early visibility.
  • To target the European community in the morning and leverage the US community who tend to upvote same projects by mimetism in the afternoon.

Friday 9:00AM — The product was live on PH.


Kickoff upvotes

On that Friday morning, I gently asked in a few Facebook and Slack tech groups to look at my PH project, and upvote if they liked it.

I made sure to follow PH best practices not to get penalized:

  • I shared PH homepage rather than my specific product page directly.
  • I reached out to people from various countries— IPs — simultaneously.

First upvotes started to flow.

The page reached its first 100 upvotes within 4 hours 🚀


And so did comments. Most were positive and showed people interest into the project:


I took the time to answer each comments.

The race was on.


The impact

After a fierce competition that day, Best Referral Programs ranked #2 on PH.

Source: Product Rank


The project received 100+ shares on Twitter.

The featured image conveyed clearly the project value 🎯

Because the project reached the top 5 that day, it was featured the next day in the “Weekend’s top hunt” newsletter, fostering its impact.


I did the math.


Driving high traffic

In total Best Referral program generated:

  • 10,499 unique visitors
  • 39,176 pages views
Live analytics on launch day, in other words.. vanity metrics 😛

The project received approx. 900 upvotes over time, that’s around 12 unique visitors per upvote.


544 people signed up for my blog newsletter using the top navigation bar email opt-in, that’s a 5% conversion rate.


Considering how wide the project spread — including on social medias — the conversion rate was above market average.


The unexpected

Now, they are a couple of things I did not expected from this project, among which 1 Affiliate program offer from a growth hacking product company. 1 Article mention as an influential founder to follow next to personalities like Ryan Hoover (Product Hunt) or Marc Köhlbrugge (BetaList). 50+ quality mentions and links to my blog (SEO backlinks!). 10+ requests to hunt people’s projects with my account. 20+ emails with additional referral programs to be added to the website.

Get the most out of it

Over the next two months these opportunities lead me to narrow down my blog positioning and kickoff its audience. Hadn’t I have been further and re-used this referral program case that I would have a missed that chance.

I was just looking back at the first point in the first paragraph:


Could I actually create virality?


I think I’ll call that a ‘yes’.
