Applied by referral and was contacted almost immediately by a recruiter. Set up a google hangouts phone screen and then set up an on-site at their Venice HQ. Phone screen was 1hr, and on-site is the usual all-day multiple interview process. The recruiters were friendly and extremely prompt. The girls who interviewed me were absolutely fantastic engineers that made the interviews interactive, open to different/new ideas, and were generally welcoming. The men who interviewed me were agressive, rude (on phone texting, checking emails right next to me, and NOT willing to change or explore new ideas), and most importantly not willing to work together. Throughout my interview I had recruiters, and engineers consistently talk down upon the android client (huge red flag). Overall, it reeked of an engineering culture that is youthful and trying to find its way. I would be careful to work here simply because a toxic culture can not be fixed from the ground up, and most importantly it impeads on the time for learning. Overall, I was able to implement each answer correctly with unit tests in the allotted time but was denied. I ended up taking another offer at a larger company in the bay-area, and would not have accepted the offer if it was given due to (what I perceived to be) a very hostile workplace. Easy interview though, just use the MVC architecture in your answers (engineers didn't know MVP/RxJava patterns).
