Alphasights Technical Challenge

Using Ruby on Rails we would like you to create a simple expert search tool. The application should fulfill the requirements below. The source code must be placed in a public repo on GitHub. The application should be deployable on Heroku.

I enter a name and a personal website address and a member is created.
When a member is created, all the heading (h1-h3) values are pulled in from the website to that members profile.
The website url is shortened (e.g. using http://goo.gl)
After the member has been added, I can define their friendships with other existing members. Friendships are bi-directional i.e. If Sasha is a friend of Ash, Ash is always a friend of Sasha as well.

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.
