When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.

Contrived example demonstrating microgem dependencies

contrived is a microgem that depends on another microgem array_range, however gemspecs don't support DVCS dependencies. So how do we solve this without prematurely denting the universe?

Just use bundler.

Usage

Add all microgems to your project's Gemfile:

to show simple steps I took to try and reproduce the described issue based upon the
information available. This is very simple benchmarking with an almost vanilla Rails 4
application using sqlite as the database so is not useful other than to demonstrate the
out of the box performance with TorqueBox and Trinidad under these situations is very
close.

Put this code on the page where the form you want to track resides. Some other examples are currently passed around the web with varying quality. This is one that will work as long as your form tag has an id= or name attribute.

You don´t have to change this code to be able to track form abandonment in your shopping cart, order form or whatever form you want.

This sends events to Google Analytics when a user focuses somewhere not in a field after having focused on a input field. You won´t know for how long users focused on respective fields, or the actual conversion rate in the form using this, but it might be a start.

A tool that provides more insight both over time and per field, is Form Analytics wich helps you optimize your online forms. For instance, it measures dropout rate, average field input length, conversion rate and average time per field. All which provides great insights in the most overlooked, yet important part of you site.

Anyway, here´s the code:
