Received phone call from one of their recruiters. Questions were basic programming questions and position sounded like a good fit. They flew me out to Colorado and paid for all travel expenses (hotel, flight, etc.) which was great. However, the interview process was very faulty and unimpressive.
There's a 32-question test which has to be completed in 30 minutes. Only two of the questions are related to programming or anything IT related at all. The next hour and half was spent in a room with one guy who didn't appear to know the basics of programming - he was confused by recursion and the modulo operator. The rest of the time was spent on whiteboard problems - some of which can be found here in other reviews.
Overall, I wasn't impressed with their process. No programming knowledge was tested at all. It makes me question how effective their development team is if they don't even spend the time to gauge potential hires in the correct way. Brain teasers do not gauge the effectiveness of a developer - coding projects are a much better way to spend the two hour interview process.
I'm convinced that if you study all of the interview questions on Glassdoor and do well on the IQ test you'll land a position - and you don't even need to have written a line of code in your life! That's a scary proposition and the reason I turned down the offer.
