Interview Process Breakdown:

• In-person lunch interview - 1 hour
• On-site tasks - 4-6 hours
• Rejection - priceless

Overall, everyone was very friendly. The office is great, and the lunch was quite decent. A lot of weight is placed on cultural fit, so be friendly and open.

After preparing for more difficult interview questions, I was completely thrown off track when asked to implement a couple of very basic iOS tasks, such as table/collection views and autolayout. There was also no boilerplate code to even get the app on screen. For an experienced engineer, who may be used to adding features to an existing application or using Xcode boilerplate code (read: most people), this was annoying and not a good measure of anything, in my opinion.

I was disappointed because I don't think the two questions I flubbed were a good representation of day-to-day skills. I was doubly disappointed because I was told there would be a paired-coding session involving debugging, etc., which sounded a lot more worthwhile.

At the end of the day, I had prepared for a senior position but was thrown by junior/entry-level questions.

Here's the text to clean up:

• Implement a simple algorithm dealing with a grid (think bucket tool in Photoshop).
• Implement it in a way that scrolls smoothly using a table or collection view.

Given an app with three screens and many components, discuss how you would implement it. This is a general screen to assess knowledge of the SDK.

Two algorithm questions (already discussed on Glassdoor):

• Think recursion for one.
• Consider how Pinterest might implement its infinite-scrolling boards for the other.

Implement a simple table or collection view with alternating cell layouts, avoiding boilerplate code.
