First you get a talk with HR, standard stuff. Then there was a one hour technical interview, which consisted of technical questions and a coding exercise. It was a little bit weird. The guy said right away that he's not a mobile dev at all, he doesn't know any frameworks or languages related to mobile and he's a web developer only knows Ruby. Then he said that regarding the exercise it doesn't matter how you do it or your style of coding, what matters is that you get it in time and the results match their test cases. So, I did everything in time, my results matched every test case that he had. In a few days I got a rejection letter, standard stuff, no explanation nothing. I asked for an additional feedback - no answer, of course. Waste of time and energy.

1. Intro call. 2. Easy coding interview. - No leetcode preparation is needed. 3. Life Story - I read a lot of your comments on glassdoor before my interview. Unfortunately, you guys are right, I got a templated declined letter after 45 mins talk. Yes, it is strange HR can decide no continue because they don't like your life story.
