New York Times IOS Developer interview questions

Recruiter approached me on Hired.com. Set up an initial phone screen then a code assessment. Completed the assessment then got a rejection a few days later. No feedback on my code assessment.

Had an easy phone interview and then was sent a problem to solve as homework. The problem was not hard - just had to download a json response, parse the response and convert the text. Didn't receive any feedback as to what they were looking for. Simply a rejection. I've been an iOS Engineer for 5 years and was stumped as to what was wrong. Another colleague went through the same process about the same time frame and he has similar iOS development experience with an MS in computer science and he experienced the same thing with his problem. It makes you wonder whether or not they are actually hiring people. I spent about 8 hours on the problem and so did my friend.
