I was contacted by the recruiter about 2 days after I had applied. A technical phone interview happened with the hiring manager.

Basic JavaScript OOP questions were asked, along with concepts like event bubbling, closures, etc. (Look for more questions below).

Then, I had a Skype session with a CSS specialist. He basically showed me a button on screen and told me to style it to look nicer and more legitimate.

Finally, I had a non-technical interview with the product manager for cultural fit.

PHONE INTERVIEW:

Given a JavaScript array like ['a', 1, null, [], 2, ['b', 'c', ['d', [[], [1, 32, 'ksdjb']], []]]]; write a function to flatten it so it looks like ['a', 1, null, 2, 'b', 'c', 'd', ...];

Create a page that allows the following logic:

• Define a field set for an arbitrary table. This field set has the mandatory field id and as many additional fields as the user desires.

• Add records. The user should be presented with a table. The user should be able to add records to the table and edit any existing record. The user should not be allowed to commit a record if its id is non-unique amongst the other records in the table.

• Export the records. The user should be able to export the records in JSON format.

This page should be runnable by a browser without access to the internet, so please keep all dependencies with the page to minimize any dependency loading difficulties.

Feel free to use any library you wish as long as it does not solve the entirety of the problem. For example, jQuery, Angular, Backbone, Underscore, etc., are all fine, but a table editing jQuery plugin would not be fine.
